Meatball subs will be the main thing and lots of little junk on the side.

4 pounds ground beef
5 ounces French-fried onions -- coarsely crushed
1 cup seasoned bread crumbs
4 eggs
1 teaspoon salt
1 teaspoon black pepper
18 ounces beef gravy
1 tablespoon prepared horseradish -- drained
26 ounces spaghetti sauce
1/4 cup grated Parmesan cheese
8 sub sandwich rolls -- split

Preheat oven to 350F. In a large bowl, combine ground beef, French-fried onions, bread crumbs, eggs, salt and pepper; mix well. Shape into 24 meatballs and place on a large rimmed baking sheet. Bake 18-20 minutes, or until cooked through and no pink remains.

In a medium saucepan, combine gravy and horseradish over low heat. In another medium saucepan, combine spaghetti sauce and Parmesan cheese over low heat. Simmer both sauces 5 minutes or until heated through, stirring occasionally. Place three meatballs on each roll and serve with sauces.
