Preheat oven to 450 degrees F.
Place the naan flatbreads on a large baking sheet. You may need to do them in two separate batches.
Mix the ricotta, garlic powder, and salt in a small bowl.
Divide the ricotta mixture evenly between the 4 flatbreads and spread thinly across the flatbread.
Add ½ cup of spinach to each flatbread, then mushrooms, and top with mozzarella.
Bake for 12-15 minutes until the cheese is brown and bubbly in some places.
Drizzle each pizza with chili onion crunch, slice, and serve!
