Preheat oven to 400 degrees F. Prepare a baking dish with cooking spray and set aside.
Cut your chicken into bite-size nuggets and set aside. In three separate bowls add flour to one, beaten egg to the second, and bread crumbs with parsley, seasoning salt, and pepper.
Place your chicken nugget into the flour and coat. Dunk into beaten egg and then coat in bread crumbs. Repeat with all nuggets and place them in your prepared baking dish.
Bake for 10 minutes flip all nuggets and return to the oven for 10 more minutes. Serve and enjoy!
