Toast the bread slices to your desired level of crispness.
While the bread is toasting, cut the ripe avocado in half, remove the pit, and scoop out the flesh into a small bowl. Mash the avocado with a fork until it reaches a smooth consistency. Season with salt and pepper to taste.
In a non-stick skillet, heat a small amount of cooking oil over medium heat. Crack the eggs into the skillet and cook them to your preference (e.g., sunny-side up, over-easy, or scrambled). Season with salt and pepper.
Once the bread is toasted, spread the mashed avocado evenly onto each slice.
Carefully place a cooked egg on top of each avocado-covered slice of bread.
Add your desired toppings, such as sliced cherry tomatoes, crumbled feta cheese, chopped fresh herbs, and a drizzle of hot sauce.
Sprinkle with additional salt and pepper, if desired.
