Heat a skillet over medium heat and lightly toast the corn tortillas until they are crisp. Set aside.
Warm the refried beans in a small saucepan or microwave until heated through.
Heat olive oil in the skillet, crack the eggs, and cook them to your preferred doneness.
Spread a layer of refried beans onto each toasted tortilla.
Top each tostada with shredded lettuce, diced tomatoes, and shredded cheese.
Carefully place a cooked egg on top of each tostada and add any optional toppings you like.
Serve immediately and enjoy your breakfast tostada!
Notes
For a vegetarian version, skip the eggs or replace with scrambled tofu. You can make tostadas gluten-free by ensuring all store-bought ingredients are certified gluten-free. Customize the toppings for added flavor or to suit your preference.
