Preheat oven to 375 degrees F. Spray a standard size muffin tin with nonstick cooking spray.
In a medium skillet, cook your meat - breaking up with a spatula - until browned. Drain any liquid from the pan (this will avoid making soggy wonton cups.)
Add the taco seasoning, and diced tomatoes and jalapenos to the skillet with the drained meat and stir to combine.
Line each cup of the prepared muffin tin with a wonton wrapper. Add 1 1/2 tablespoons of the taco mixture, then top with a tablespoon of cheese. Add another wonton wrapper on top, and press down to flatten the lower layer some, then fill with another 1 1/2 tablespoons of taco mixture and top with cheese.
Bake at 375 for 11-13 minutes until cups are heated through and edges are golden. Allow to cool for a few minutes before carefully removing from the muffin tin (I used a small spoon to help me, in case any edges were stuck to the tin), top with your favorite toppings, and enjoy!
