To prevent the avocado from browning, sprinkle the slices with a little lemon or lime juice before adding them to the hot pizza.
You can substitute the buttermilk baking mix with a quick bread mix or make a simple dough from flour, yeast, and water if preferred.
For extra heat, add a pinch of red pepper flakes to the tomato sauce mixture.
Leftovers can be stored in an airtight container in the refrigerator for up to 2 days, though the avocado may darken slightly.
