All you need for this is some string cheese and an oven. If you are going to have light string cheese as a snack anyways, why not mix it up a bit? Process
1. Slice the string cheese into nickle-sized pieces.
2. Arrange on a baking sheet and bake at 350 degrees until the cheese is becoming golden.
3. Remove from oven and let cool. The cheese will be crispy and airy.
