TWO uses for an upside-down muffin tin in the space of one week! Mini Taco bowls Directions: 1. Preheat the oven to 375. 2. Sprinkle each tortilla lightly with water and stack them on a plate. Cover the top with another plate turned upside down and microwave the tortillas for 1 minute or until warm. Turn two 12 cup muffin pans upside down. Mist each side of a tortilla lightly with cooking spray and center it in the space between 4 muffin cups, creating a bowl. Repeat with the 5 remaining tortillas, forming 3 bowls on each tin (as pictured above). Bake in the oven for 8-10 minutes.
