Fill your cast iron with at least two inches of oil. Heat it over medium heat as you prepare the chicken.
Mix flour, pepper, garlic powder and salt in one bowl.
Using another bowl, mix the egg and lemon juice.
In a third bowl, mix the panke breadcrumbs with parmesan cheese.
Coat chicken with flour; dip into egg mixture, then coat with bread crumb mixture.
Drop some flour to help you know the temperature of the oil. If it sizzles immediately, you add the flour - go ahead and start putting in the chicken tenders.
Fry the chicken in small batches for 8-10 minutes or until golden brown.
After removing them from the fire, place them on a plate with paper towels and add more salt if you feel like it.
