These are so easy to make. They take just a few minutes and you will add the "wow" factor to a salad. The only ingredient you need is the Parmesan cheese, and only three basic tools are required: a pan (I used non-stick, but steel or cast iron would work as well), a spatula (either metal or a latex spatula that is designed for high heat), and a mold (I used a roll of aluminum foil, but an inverted cup or glass works just as well).
So here's how to make them. Heat the skillet over medium heat. Sprinkle a liberal amount of cheese into the pan and wait until it melts, bubbles, and the bottom begins to brown. Then gently slide it out of the pan and onto the mold. After the cheese cools it will retain the shape of the mold and can be filled with salad. Simple as that.
