Customize: add toppings like refried beans, pinto beans, lettuce, cabbage, tomatoes, pickles, cheese, and salsa.
Experiment: try different tortillas, different oils or even adding spices after frying like chili powder for varied flavors. These also make for a delightful breakfast with beans and fried eggs.
Storage: store any leftover tostadas in an airtight container for 2-5 days.
Tortilla chips or strips: the same method above can be used to make tortilla chips or strips by cutting the tortilla into pieces before frying.
