Preheat your oven to 350°F (175°C). Place the tostada shells on a baking sheet and bake for about 5-7 minutes until they are crispy.
In a large bowl, combine the shredded rotisserie chicken, black beans, corn, lime juice, chili powder, and season with salt and pepper. Mix until well combined.
Take the toasted tostada shells out of the oven and let them cool slightly.
Begin assembling your tostadas by spreading a generous layer of the chicken mixture onto each tostada shell.
Top each tostada with diced avocado, cherry tomatoes, red onion, shredded lettuce, and crumbled queso fresco.
Garnish with fresh cilantro and an extra squeeze of lime juice, if desired.
Serve with a dollop of sour cream or Greek yogurt on the side for an extra creamy element.
Notes
Serve with sour cream or Greek yogurt for added creaminess.
