Here we’re using leftover refried beans, but you can use canned refried beans.
Smear refried beans to a tostada. Add the cheese, lettuce, and tomatoes. Since the beans are warm, the cheese will melt slightly.
Feel free to use any salsa you enjoy. Salsas made in molcajetes are chunky, but others made in the blender are smooth in texture.
If you don't serve them right away, the salsa and beans will make soggy your tostadas. Bean Tostadas are so satisfying, enjoy!
