Line a baking sheet with silicone mat or parchment paper.
Place 1/3 cup piles of cheese 3 inches apart on the prepared baking sheet.
Bake the first batch for 5-7 minutes or until the cheese melts and turns lightly brown.
Let the cheese cool for 2-3 minutes then using the spatula lift it up and place it over the handle of a tong or other utensils that is balanced on two cups.
Repeat with the remaining cheese circles.
Fill the shells with your favorite taco fillings and serve.
