1Heat oil in large skillet over medium heat. Add onion, cook and stir until tender. Add your turkey or ground beef and cook until no longer pink, stirring to break up meat. Stir in garlic, oregano, chili seasoning or taco seasoning and salt. Remove from heat and stir in 1/2 cup cheese. Set aside.
2Preheat oven to 375 degrees. Lightly grease 36 mini (1 3/4-inch) muffin cups. Remove dough from container but do not unroll dough. Separate dough into 8 pieces at perforations. Divide each piece into 3 pieces, roll or pat each piece into 3-inch circle. Press circles into prepared muffin cups.
3Fill each cup with 1 1/2 or 2 teaspoons of meat mixture. Bake 10 minutes. Sprinkle tops of taco cups with remaining 3/4 cup cheese. Bake 2 to 3 more minutes or until cheese is melted. Garnish with tomato and green onions, if desired.
