1-2cupsshredded cheddar or Monterey jack cheese, or a combination
Taco toppings like lettuce, tomatoes, sour cream, olives, etc.
Preheat the oven to 375 degrees F.
Lightly grease two muffin tins. Cut 4-inch circles (using a cookie cutter or a round shape, like a lid, you can cut around with a knife or kitchen shears) from the tortillas. You'll need about 16. Microwave the cut tortillas for about 10-15 seconds until pliable. Nestle one tortilla in each muffin tin, pressing the tortilla into the bottom and corners of the tin. Set aside.
In a large nonstick skillet, cook the ground beef or turkey, salt and pepper over medium heat, breaking up the meat into small pieces, until cooked through 5-8 minutes. Drain any excess grease. Stir in the chili powder, cumin and tomato sauce. Bring the mixture to a simmer and cook for 3-5 minutes.
Scoop a spoonful of meat and sauce into each tortilla cup. Top with a sprinkle of cheese. Bake for 10-12 minutes until the tortillas are lightly golden around the edge and the filling is hot and bubbly. Carefully remove the cups from the muffin tin and serve with any taco toppings of your choice.
Tortillas: if you can't get your hands on 10-inch tortillas, feel free to use smaller sized tortillas, just plan on needing more than 4-5 since you'll probably get fewer circles cut out of each tortilla. Refried Beans: if you'd like to make the meal even heartier and stretch the meat mixture, try spooning in a teaspoon or so of refried beans into the bottom of each tortilla cup before adding the meat/sauce mixture.
