Preheat oven to 250°. Lightly spray tortillas with cooking spray. Bake until tortillas are crisp and starting to brown, about 5 minutes.

In a microwave-safe bowl, combine refried beans and green chiles. Heat covered for 1 to 2 minutes until the beans are warm.

Spread warm refried beans on crisp tortillas and top with lettuce, cheese, guacamole and salsa. Serve immediately.
