Start by selecting a ripe avocado that yields slightly when pressed. Slice it in half and carefully remove the pit. Use a spoon to scoop the creamy avocado flesh into a bowl. Mash it gently with a fork until you achieve your desired level of creaminess, leaving some small chunks for texture if you prefer.

Add 1 to 2 teaspoons of lemon or lime juice to the mashed avocado to enhance flavor and prevent browning. Sprinkle in ¼ to ½ teaspoon of garlic powder and a pinch of salt to taste. Stir the mixture thoroughly until all the elements are well combined.

Prepare your choice of sourdough or whole-grain bread by toasting about 2 slices until they are golden brown and crispy.

Once the bread is toasted to perfection, spread the mashed avocado mixture generously over each slice, ensuring every bite is packed with flavor.

Sprinkle finely chopped red onion evenly across the avocado spread. Add chopped cilantro or coriander leaves, and if you like, sprinkle red pepper flakes to your taste.
