Toast the bread slices until golden brown and crispy, about 3-4 minutes in a toaster.

Cut the avocados in half, remove pits, and scoop into a bowl. Mash with a fork until smooth. Add lemon juice, salt, and pepper, then mix well.

Slice cherry tomatoes and chop olives. Crumble feta cheese. Slice basil leaves. Set aside.

Spread the mashed avocado evenly onto each toasted bread slice. Top with cherry tomatoes, olives, feta, and basil leaves. Drizzle with olive oil.
