Cook the mini tart shells according to the package instructions.
While the shells are cooking, brown the ground beef.
When the beef is cooked through, stir in the taco seasoning and water. Continue to simmer until the sauce is thickened. Remove the pan from heat and allow to cool.
Fill each tart shell with taco meat and top with shredded cheese.
Return the shells to the oven to cook until the cheese is melted, about five minutes.
Allow the mini taco pies to cool completely, then transfer them to a freezer bag.
Remove excess air from the bag and seal. Freeze.
Oven Cooking Instructions:
Thaw.
Place the cups in the oven to bake at 350° for 10 to 15 minutes, until the meat is warm and the cheese is melted.
Microwave Cooking Instructions:
Take as many cups as you want out of the freezer.
Remove the foil and reheat in the microwave.
Notes
If you have any of the taco meat mixture leftover, place it in a medium size freezer bag, seal, and freeze. You can then use it to add to eggs or hash browns, on top of nachos, or for tacos.
