Preheat oven to 350°F. Cut approximately 4 inch circles out of each tortilla and place each circle into a muffin pan.

Bake tortillas for 12 minutes.

While tortillas are baking, add beef to large skillet over medium heat.

Stir in taco seasoning and heat until beef is thoroughly browned.

Leaving tortilla cups in the muffin pan add beef evenly to each cup followed by salsa, olives and cheese.

Bake for another 5-10 minutes or until cheese is melted.

Top with sour cream immediately before serving.
