Toast the sourdough bread slices in a toaster or on a skillet over medium heat until golden brown and crispy.

While the bread toasts, cut the avocado in half, remove the pit, and scoop the flesh into a small bowl.

Mash the avocado with a fork until it reaches your desired consistency, leaving it slightly chunky for texture.

Stir in the olive oil, a pinch of salt, and freshly ground black pepper into the mashed avocado.

Spread the avocado mixture generously over the hot toasted bread slices.

Top with the halved cherry tomatoes and sprinkle the crumbled feta cheese evenly over the toast.

Drizzle the balsamic glaze over the toppings and add a pinch of red pepper flakes for a gentle kick.

Garnish with fresh basil leaves and serve immediately.
