Cut string cheese in half crosswise.
Beat 1 egg in small bowl. Set aside.
Place Nut Crumbs, Parmesan cheese, garlic powder, and salt in zipper sandwich bag. Shake bag to blend.
Dip each piece of mozzarella into the beaten egg and then coat by shaking in the sandwich bag. Freeze for at least one hour.
Heat oil in small frying pan to at least half inch high. Temperature of oil should be about 325-375°F. Higher temperatures tend to brown too quickly with cheese melting out. Air frying works too using a temperature of about 370 to 400°F for about 5 to 7 minutes.
Cook each coated piece of mozzarella in the hot oil until browned on all sides. Enjoy!
