◈  Make the meatballs: Preheat oven to 400°F. Add half the hot sauce mixture to a medium bowl with chicken, panko, egg, celery, parsley and garlic powder. Season with salt and pepper and mix together well; if mixture is too wet, add a bit more panko. Form 12 golf-ball-size meatballs. Place them on a parchment-covered baking sheet and bake until cooked through, 18 to 20 minutes.

◈  Make the sub: Toast roll, place two slices of cheese on bottom half, and place 3 meatballs on top. Place two more slices of cheese on top of meatballs and return to oven to melt cheese. Top with remaining hot sauce mixture before serving.
