Heat oven to 400°F. Mix beef, breadcrumbs, egg, Parmesan, garlic powder, Italian seasoning and 2 tbsp water. Roll into 16 meatballs.
Bake meatballs on a lined sheet pan 15 minutes until cooked through (160°F).
Warm the marinara in a large skillet and roll the baked meatballs in it to coat.
Split rolls, line with provolone, and add 4 saucy meatballs each.
Bake 4-5 minutes until the cheese melts and the bread is toasty.
