Leftover Turkey Tostadas | Kaiser Permanente

Preheat oven to 375 degrees.In a medium saucepan, cook tomatoes and jalapeños until soft over medium heat. Add onion and cook, stirring occasionally, until the onion is soft and most of the liquid has evaporated, 15 to 20 minutes. Add turkey and cook until heated through about 1 to 2 minutes. Set aside. Coat tortillas on both sides with the cooking spray. Divide the tortillas between 2 large baking sheets. Bake, turning once, until crisped and lightly brown, about 10 minutes. In a small bowl, mash avocado. Stir in salsa, sour cream, and cilantro until combined. To assemble tostadas, spread each tortilla with some of the avocado mixture. Top with the turkey mixture, lettuce, and cheese.
