Spread about 2 tablespoons black bean hummus over the top of each tostada. Bake for 3 to 5 minutes.
*I use Lantana brand. Feel free to swap out the hummus for black refried beans or regular refried beans, if preferred. Other flavor varieties of hummus could be used too.
**You can buy this premade in the produce department of most grocery stores.
***All toppings are optional. Use your favorites!
