Stir together the black pepper, paprika, salt and garlic powder in a bowl. Rub chicken with half the seasonings, then stir the remaining seasonings into the flour in a bowl. Let seasoned chicken rest in fridge 8 hours or up to overnight.
Preheat oil in a deep-fryer to 350 degrees F.
Dredge seasoned chicken in the seasoned flour. Fry until cooked through, 10 to 20 minutes. Place chicken in fridge until chilled, 1 to 2 hours.
Split open hoagie rolls without cutting all the way through. Slice chilled chicken and glaze with onion dressing. Assemble sandwiches with mayo first, then veggies, then chicken. Enjoy!
