Easy Breakfast Sandwich

This Easy Breakfast Sandwich recipe is one of my all-time favorite things to eat in the morning. It is quick, healthy and so good, it’ll knock your socks off.

The creamy avocado, fresh tomato and rich runny egg yolk surrounded by a crispy English muffin is what breakfast sandwich dreams are made of. I’m not going to like, this is a messy sandwich but in the BEST way. So have a napkin handy!

How to Make a Breakfast Sandwich Your Own

Use Different Greens – The breakfast sandwich I photographed for this post used microgreens simply because I like them. You can use whatever greens you prefer like spinach or arugula. Sprouts would be really good too! If greens aren’t your thing, omit them altogether. You’re the chef after all!

Reduce Avocado If Needed – This recipe uses 1/2 an avocado per one sandwich. If you are looking to reduce calories or other things of that sort, simply use 1/4 an avocado!

Use Different Egg Preparation – The instructions of this recipe are for a sunny side up egg. This is where the egg white is completely cooked through but the egg yolk is not. So when you bite into the breakfast sandwich the rich delicious egg yolk breaks open and almost acts like a sauce for the whole sandwich. It is divine and SO easy! No, flipped, timing or guessing required (see below for detailed instructions). I highly recommend you give it a try, but you can cook the egg however your want (scrambled, poached, hard-boiled, etc.) and it will still be good in this recipe.

Quick Egg Tip – To keep bits of shell from ending up in your sandwich, crack eggs on a flat surface, not the edge of a counter, bowl or pan. As an added bonus, this method also helps prevent cross-contamination.

Helpful Hints

Are egg sandwiches healthy?

This one is! We pack a bunch of fresh and nutritious ingredients into one little breakfast sandwich. For starters, we’ve got fresh tomatoes and greens. There’s healthy fat from the avocado. A bit of protein from the egg. To top it off we put all this delicious goodness inside a warm whole-wheat English muffin. Delicious and healthy!

What type of pan is best for eggs?

In general, a non-stick pan is a good option for making eggs but a ceramic non-stick pan is even better! My personal favorite when making eggs is the GreenPan which is a ceramic non-stick pan. I first used a GreenPan at my friend Shell’s house and loved it so much, I immediately went home and purchased a couple for myself. Eggs cook perfectly every single time and they slide out of the pan with such ease, it is almost hard to believe. This pan is awesome and you should get one.

HOWEVER, there are a couple minor tricks to know. Do not, under any circumstance, use cooking spray on a GreenPan. It will burn and the residue will create a barrier between the non-stick surface and your food which will cause your food to stick like crazy. Second, keep the pan nice and clean. If at any point your food starts sticking, chances are the pan just needs a good scrub to remove any leftover residue from prior uses. I love this pan so much. Can ya tell?

How to make eggs sunny side up

The egg in this breakfast sandwich is sunny side up. Don’t let that intimidate you! Sunny side up eggs are the easiest and tastiest way to prepare eggs (in my opinion). Put a non-stick pan on the stove over medium heat. Melt a tiny bit of butter in the pan (around 1/4-1/2 tsp.). Then simply crack an egg into the pan. That is it. You don’t need to touch it or flip it or anything. Just let it sit there and cook. When the egg white portion has completely cooked through but the egg yolk is still bright yellow and runny, it is done! Remove the egg from the pan with a spatula and put it on your breakfast sandwich!

Other Healthy Egg Breakfast Recipes

I’ve rounded up a few other healthy egg breakfast recipes. First we have Southwest Egg Cups which are perfect for meal prep!

Then we’ve got Avocado Egg Salad Breakfast Toast which takes 5 minutes to put together if you hardboiled eggs ready to rock and roll! I make my hardboiled eggs in the oven. It is so easy and they come out perfect every single time!

Last we have a Tomato Spinach & Goat Cheese Crustless Quiche which is the best of both worlds! You can serve it for brunch or make it ahead of time for breakfasts on-the-go!

  • Slice Tomato: Cut the cherry tomatoes in half. Set aside. 
  • Mash Avocado: In a small bowl mash the avocado, salt and lime juice with a spoon until you've reach your desired consistency. Personally, I like my avocado nice and chunky. Set aside. 
  • Fry Egg: Put a nonstick pan over medium heat. Put a tiny bit of butter in the pan (like 1/4-1/2 tsp). Once the butter has melted, crack your egg into the pan. Let it cook for 2-3 minutes or until the egg white is entirely cooked through but the egg yolk is still nice and runny. Not need to flip the egg! Once done, remove it from the heat immediately.

    This recipe is DELICIOUS. I tried this out a couple of weekends ago and now have it every Sunday. I normally have all of the ingredients on hand anyways, so it is really easy to whip up. The lime juice is my favorite; really brings out the flavors!

  2. Oh my… this is one delicious looking sandwich. I really wish I could grab it from the screen right now. I must save this recipe and give it a try this week. My hubby is fan of breakfast sandwiches too so we will be enjoying these that’s for sure.

    1. I hope you and your hubby enjoyed it! Whenever I make my husband a sandwich he is happy as a clam and this sandwich is no exception! 🙂

  3. This is a seriously, seriously delicious looking breakfast sandwich! I love runny yolks – even if they make sandwiches just a tad bit messy. 😉

    Sunny side up eggs are the best, especially on a sandwich! This sandwich looks delicious, and perfect for weekend breakfast. I don’t have a green pan, but I just bought a mini cast iron skillet and it also works great for cooking an egg

    1. I have a standard size cast iron skillet but a mini one sounds so fun but also efficient for something quick like a couple eggs. I might have to get one myself! Thanks for sharing!

    That runny egg is so perfect! I’m also a huge fan of microgreens but they’re hard to find here. Might have to start growing my own so I can make this!

    1. Microgreens are challenging to find at times in Minnesota as well, especially in the winter! I’ve never thought of growing my own but I grow my own herbs. So, I might just grow my own as well! Thanks for the idea!
