Step 1: Prepare the Chicken – Heat olive oil in a skillet, add the cooked chicken, and season with cumin, chili powder, salt, and pepper. Stir for a few minutes until fragrant and well-coated.
Step 2: Warm the Refried Beans – In a small pan, reheat the beans, stirring occasionally until smooth. If they’re too thick, mix in a little water or broth.
Step 3: Crisp the Tostadas – Place tostada shells in the oven for a few minutes until crisp and warm.
Step 4: Assemble – Spread a layer of refried beans on each tostada. Add a spoonful of chicken and then top with lettuce, tomatoes, onion, cheese, avocado, and any preferred toppings.
Step 5: Finish and Serve – Drizzle with sour cream, add cilantro, and serve with lime wedges on the side.
