1) Line a baking sheet with parchment paper and portion out cheese into about 1/2-ounce piles. Do six per baking sheet.
2) Add baking sheet to a 350° F. oven and let bake so cheese melts. Bake for 10-15 minutes. Turn baking sheet so the taco shells bake evenly. When the cheese starts to brown on the edges and the bubbles solidify on the cheese, they are done.
3) Work quickly now. While your cheese is still flexible, add the taco shells to an upside-down muffin tin. Use the muffin tin holes to keep the shells in place. Let cool completely.
4) Fill cheese taco shells with light toppings. I like a simple mix of lettuce, chopped bacon, and tomatoes. Yum!
