Slice the avocado in half, remove the pit, and scoop the flesh into a bowl. Use a fork to mash the avocado until it reaches your desired consistency. Season with a pinch of salt and pepper to taste.
In a non-stick skillet, melt a small amount of butter or add a drizzle of olive oil over medium heat.
Crack the eggs into the skillet and cook them to your preferred doneness (fried, scrambled, or sunny-side-up). Season the eggs with a pinch of salt and pepper while cooking.
Once the eggs are cooked, remove them from the skillet and set them aside.
Toast the bread slices until they reach your desired level of crispiness.
Spread the mashed avocado on one slice of toasted bread.
Place the cooked eggs on top of the avocado.
Close the sandwich with the other slice of toasted bread.
Press the sandwich gently together.
If desired, you can slice the sandwich diagonally into halves or quarters for easier eating.
Serve the Avocado Egg Sandwich immediately while the eggs are still warm and enjoy this delicious and nutritious treat!
