Chicken and Summer Vegetable Tostadas

4 servings
Preheat broiler.
In a large skillet over medium-high heat, heat oil. Combine cumin, salt and pepper and sprinkle over chicken or other protein. Add chicken to pan, sauté for 3 minutes. Add onion, corn, and squash to pan; sauté for 2 minutes or until chicken is done. Stir in salsa and 2 tablespoons cilantro. Cook 2 minutes or until liquid almost evaporates, stirring frequently.
Working with 2 tortillas at a time, arrange tortillas in a single layer on a baking sheet; lightly coat tortillas with cooking spray. Broil 3 minutes or until lightly browned. Spoon about 3/4 cup chicken mixture in the center of each tortilla; sprinkle each serving with 1/4 cup cheese. Broil an additional 2 minutes or until cheese melts. Repeat procedure with remaining tortillas, chicken mixture, and cheese. Sprinkle each serving with about 3/4 teaspoon of remaining cilantro. Serve immediately.
