Equipment

  • slow cooker

Ingredients
  

For the Meatballs

  • 1 lb Ground Beef
  • 1/2 lb Ground Italian Sausage
  • 1/3 cup Italian Breadcrumbs
  • 1/4 cup Grated Parmesan Cheese
  • 1 Large Egg
  • 3 cloves Garlic, minced
  • 1 tsp Italian Seasoning
  • 1/2 tsp Salt
  • 1/4 tsp Black Pepper

For the Sauce & Assembly

  • 24 oz Marinara Sauce (1 jar)
  • 1/4 tsp Red Pepper Flakes
  • 6 Sub Rolls, split and toasted
  • 1.5 cups Shredded Mozzarella Cheese
  • Fresh Basil Leaves, for garnish

Instructions
 

  • In a large bowl, combine the ground beef, ground italian sausage, italian breadcrumbs, grated parmesan, egg, minced garlic, italian seasoning, salt, and black pepper. Mix gently until just combined. Roll the mixture into about 20 meatballs, roughly 1.5 inches each.
  • Pour about half of the marinara sauce into the bottom of the slow cooker. Arrange the meatballs in a single layer on top of the sauce.
  • Pour the remaining marinara sauce over the meatballs and sprinkle with red pepper flakes.
  • Cover and cook on low for 6 to 7 hours or on high for 3 to 4 hours, until the meatballs are cooked through and tender.
  • Load 3 to 4 meatballs into each toasted sub roll and spoon extra marinara sauce from the slow cooker over the top.
  • Top each sub with a generous handful of shredded mozzarella cheese. Place under the broiler for 1 to 2 minutes until the cheese is melted and bubbly.
  • Garnish with fresh basil leaves and serve hot.
