Meatball Heroes

6 sandwich rolls
1 teaspoon olive oil
30 frozen, precooked Italian meatballs
Jar of pasta sauce (I use Prego)
10 ounces shredded mozzarella
3 ounces shredded or grated Parmesan

Heat oven to 250 degrees. Warm the rolls on the oven rack. Meanwhile, heat oil in a large skillet over medium heat. Add the meatballs and cook until browned on all sides. Add the sauce, reduce heat, and simmer for 3 minutes. Put 5 meatballs and sauce in a roll, top with cheese mixture.

Frozen Mamas: defrost meatballs and sauce and reheat in a sauce pan. Warm rolls, add 5 meatballs and sauce per roll, top with cheese mixture.
