Step 1: Prepare the Avocado : Cut the avocado in half, remove the pit, and scoop the flesh into a bowl. Mash with a fork until slightly chunky. Add lemon juice, salt, and black pepper to taste. Set aside.

Step 2: Toast the Bread : Toast sourdough slices until golden brown and crisp.

Step 3: Assemble the Toast : Spread the mashed avocado evenly on each slice of toasted sourdough. Top with halved cherry tomatoes. Sprinkle crumbled feta over the tomatoes. Drizzle with olive oil if desired. Season with extra salt, black pepper, and optional chili flakes. Garnish with fresh basil or microgreens for added flavor and color.

Step 4: Serve : Serve immediately while the toast is warm and crispy.
