Creating Chicken Tostadas is simple if you follow these steps:

1. Prepare the Ingredients: If you haven’t already, shred the cooked chicken and dice the vegetables.
2. Season the Chicken: In a bowl, mix the shredded chicken with chili powder, garlic powder, onion powder, salt, and pepper. Set aside.
3. Fry the Tortillas: Heat vegetable oil in a skillet over medium heat. Fry each corn tortilla for about 1-2 minutes on each side until golden brown and crispy. Drain on paper towels.
4. Spread the Beans: Take a crispy tortilla and spread a layer of refried beans on top.
5. Layer the Chicken: Add a generous amount of your seasoned chicken on top of the beans.
6. Add Fresh Toppings: Pile on the lettuce, diced tomatoes, and avocado slices for a refreshing crunch.
7. Drizzle Sauce: Top each tostada with a dollop of sour cream and a spoonful of salsa.
8. Serve Immediately: Serve the tostadas while they are still hot to retain the crunchiness of the tortillas.
