This is my absolute FAVORITE vegetarian breakfast sandwich. Ever. It has Sriracha mayonnaise. It has mashed avocado. And it has the most perfect sunny-side up egg with a runny yolk. Topped with some fresh cilantro, a little bit of lime juice, some red onion, and salt/pepper, it’s bursting with delicious flavor and hearty nutrients that will get you going for the day!
There are some perks to being a food blogger. Sometimes you get free stuff, which is great, and the BEST is when friends with chickens unload their gorgeous farm fresh eggs onto you. I knew I had to do something extra special with these colorful beauties, starting with these vegetarian breakfast sandwiches.
What should I make next? Quiche? Shakshuka? All of the above?? Oh man, I am way too excited about these eggs. Please share what you think I should make in the comments!
Sunny-side-up is my favorite way to eat eggs. With a perfectly round runny yolk and buttery, somewhat crispy edges to the whites, it’s perfect for this sandwich. But it’s messy. You’re going to want a napkin (or five) for this one.
I make my sunny-side-up eggs in a nonstick skillet in butter. First, I melt the butter over medium-high heat. Then, I crack the egg carefully (!) directly into the skillet, being careful not to damage the yolk. I turn the heat down, cover the pan, and wait for the whites to set for about 2 minutes. Covering is key here- it traps the heat in and ensures the white top of the egg cooks in a shorter amount of time, so the underside and yolk don’t get overcooked.
Don’t like a runny egg yolk? No judgement here. I suggest purposefully breaking the yolk when you add it to the pan, or cooking it a bit longer, until it’s the desired doneness.
There’s one more trick to making this sandwich absolutely perfect, and it has to do with the avocado. Whenever I slice avocado and add it to a sandwich or burger, it looks pretty, but it always squishes out the sides when I take a bite. Instead of slicing the avocado for this recipe, I mashed it into the bread slice with a fork. This makes it stick a bit better and ensures you get some in every bite.
Make sure you season that avocado with plenty of salt and a squeeze of lime juice!

Here’s the recipe for the BEST vegetarian breakfast sandwich EVER. Hope you like it as much as I do!
The BEST Vegetarian Breakfast Sandwich
- 2 slices multigrain bread toasted
- 1 tablespoon mayonnaise
- 1/2 teaspoon Sriracha hot sauce
- 1/2 tablespoon butter olive oil can also be used
- 1 egg
- 1/2 cup avocado (about 1/2 of a small avocado)
- 1 teaspoon fresh cilantro chopped
- 1 teaspoon red onion finely diced
- 1/2 teaspoon lime juice from a small wedge
- kosher salt to taste
- black pepper to taste
- In a small bowl, mix the mayonnaise (1 tablespoon) and Sriracha (1/2 teaspoon) together. Set aside.
- Melt the butter (1/2 tablespoon) in a nonstick skillet over medium-high heat. Crack the egg carefully into the pan so the yolk doesn't break (see notes). Turn the heat to medium-low and cover the skillet, cooking the egg for about 2 minutes, or until whites are set and yolk is done to the desired consistency.
- Meanwhile, spread the Sriracha mayo mixture on the two slices of toasted bread.
- Using a spoon, scoop the avocado from the peel and add to one slice of bread. Use a fork to mash the avocado evenly onto the bread.
- Squeeze the lime juice (from 1 wedge) on top of the avocado and top with kosher salt to taste.
- Place the egg on top of the avocado.
- Sprinkle the cilantro (1 teaspoon) and red onion (1 teaspoon) on top of the egg. Season to taste with salt and pepper.
- Place the other piece of bread on top of the assembled sandwich.
- Eat! With a napkin- it gets messy.
- This recipe yields ONE sandwich. Double it for two, quadruple it for four, etc.
- Don't be too concerned about the measured amount of ingredients for this recipe- it's just a sandwich. Add as much mayo, Sriracha, or cilantro as you want!
- Don't like a runny yolk? Break the yolk as you fry it, and cook until solid if you prefer.
