Chipotle Chicken Tostadas

Preheat the oven to 400 degrees F (200 degrees C). Spray both sides of each tortilla with cooking spray; place on a baking sheet.

Bake tortillas in the preheated oven until crisp and lightly browned, 6 to 8 minutes.

While tortillas are baking, combine tomato, green onions, lime juice, and cilantro in a bowl; set aside.

Mix cream cheese and chipotle pepper in a separate bowl until well blended. Remove tortillas from the oven. Spread mixture over tortillas; top with chicken and cheese.

Return tortillas to the oven and continue baking until cheese is melted, about 5 minutes. Top with the tomato mixture, olives, and sour cream.
