Place a sheet of parchment paper (NOT waxed paper) on a microwavable plate.
Add 1/3 cup of cheese to the center and spread it out into a circle.
Cook on high power for 1 minute to 1 minute 20 seconds, until the cheese starts browning a bit.
Take it immediately out of the microwave and holding the parchment paper, shape the cheese into a taco shell shape. You can prop your shell in between two glasses, jars or cans of food until it sets.
After a few minutes once the shell has hardened, remove it from the paper, fill it with taco filling and enjoy!
