Warm, cheesy and totally tasty, these easy subs make a great addition to your usual camping menu. Make it easy by cooking your meatballs at home before heading to camp.

Grilled Meatball Subs


  • ½ cup finely minced onion
  • 2 garlic cloves, minced
  • ½ cup Italian breadcrumbs
  • 1/3 cup grated Parmesan
  • 1 egg
  • 3 Tbsp. milk
  • 1 tsp. salt
  • ½ tsp. pepper
  • 2 Tbsp. minced parsley
  • 1 pound ground beef
  • 1/4 pound Italian sausage
  • 5 sturdy hoagie buns
  • 1/3 cup melted butter
  • ½ tsp. garlic powder
  • 2 1/2 cups marinara sauce
  • 3 cups shredded mozzarella or Italian cheese blend
  • Heavy-duty aluminum foil



  1. Make meatballs ahead. Preheat oven to 400°F. Line a baking sheet with parchment paper or spray with cooking spray. In a large bowl combine onion, garlic, Italian breadcrumbs, Parmesan, egg, milk, salt, pepper and parsley. Add ground beef and Italian sausage and gently combine, being careful not to overmix or the meatballs will be tough.
  2. Scoop into 1 1/2-inch balls and arrange on baking sheet. Bake for 18-20 minutes, until meatballs are cooked through. If not using immediately, cool and refrigerate in a sealed container.
  3. At camp: Preheat grill to 350°F. Melt butter and add garlic powder. Brush buns with garlic butter and grill until lightly toasted.
  4. Divide meatballs between buns, top with marinara sauce and lots of cheese. Wrap each sandwich in heavy-duty foil. Turn off one side of the grill and arrange wrapped sandwiches on the unlit side (indirect heat). Close grill and heat sandwiches until meatballs are hot and cheese has melted, about 20 minutes.
