Vegetarian Breakfast Sandwich: From Prep to Plate

Now that you have your ingredients and tools ready, let’s get cooking!
Step 1: Prepare the Ingredients
Start by slicing the ciabatta bun or English muffin in half. If you choose to use red onion, slice it thinly. Slice or mash the avocado and set it aside. This is also a good time to wash the baby spinach if you’re including it.
Step 2: Toast the Bun
Toast the ciabatta bun or English muffin until it’s golden brown. This will add a lovely crunch to your sandwich and help hold up the ingredients.
Step 3: Cook the Egg
In a non-stick skillet, melt the unsalted butter over medium heat. Pour in the beaten egg, season with salt and black pepper, and let it cook undisturbed for about 2-3 minutes or until the edges start to set. Use a spatula to gently stir the egg, allowing it to cook through without becoming dry. Aim for a fluffy texture.
Step 4: Assemble the Sandwich
Spread the mayonnaise on the bottom half of your toasted bun. Layer on the mashed or sliced avocado, followed by the cooked egg. Next, place the slice of cheese on top of the egg, allowing it to melt slightly from the heat. If you’re using spinach, layer it on next, followed by the thinly sliced red onion. Cap it off with the top half of the bun.
Step 5: Serve and Enjoy
Serve your Vegetarian Breakfast Sandwich warm, perhaps with a side of fresh fruit or a light salad. Enjoy the burst of flavors and the satisfaction of a delicious homemade meal!
