Preheat oven to 375 degrees. Combine vegetables, set aside. In a separate bowl, combine eggs, milk, and garlic powder. Cook egg mixture in a nonstick skillet until set. Place 5 tortilla shells on a non-greased cookie sheet.
Divide cheese, evenly distributing on tortilla shells. Top the tortillas with vegetables, cooked egg mixture, and bacon. Top tortillas with the remaining cheese and another tortilla shell. Bake for 5 minutes. Cut and serve.
