01 - Toast the bread slices until golden and crispy, using a toaster or skillet.
02 - While the bread toasts, cut the avocado in half, remove the pit, and scoop the flesh into a bowl. Mash with a fork, then add lemon juice, salt, and pepper to taste.
03 - Heat the olive oil or butter in a non-stick skillet over medium heat. Crack the eggs into the skillet and cook to your preference — sunny side up, over easy, or poached — seasoning with salt and pepper.
04 - Spread the mashed avocado evenly over the toasted bread slices.
05 - Place a cooked egg on top of each avocado toast.
06 - Add extra toppings like chili flakes, cherry tomatoes, or fresh herbs, if desired.
07 - Serve immediately while warm.
