Brush each slice of bread with olive oil or butter, then toast in a hot skillet or toaster until the edges turn golden brown and crisp, about 3–4 minutes.

Scoop soft avocado into a bowl, add a squeeze of lemon juice and a pinch of salt and pepper, then mash until slightly chunky yet silky.

Heat butter in a nonstick skillet over medium heat, crack in eggs, and cook until whites set but yolks stay runny, about 2–3 minutes.

Spread a generous layer of avocado mixture on each golden slice, then gently slide the warm egg on top.

Garnish with red pepper flakes, cherry tomatoes, microgreens, or everything bagel seasoning.
