Pepperoni Pizza Meatball Subs

We love meatball sandwiches so I knew this would be a hit in out house! Meatballs plus pepperoni! Sold! This recipe is adapted from Lauren's Latest!

2 tbsp olive oil
1/4 cup finely diced onion
2 cloves minced garlic
salt & pepper to taste
1/4 tsp dried basil
1 pound ground beef
2 cups pizza sauce
1/2 cup water
1 1/2 cup grated mozzarella cheese
20 slices pepperoni
4 sub rolls

In a mixing bowl combine the ground beef, diced onion, garlic, basil, salt and pepper.  Form into meatballs.  Heat oil over medium heat and saute meatballs for 2 minutes on each side. Add the pizza sauce and turn down heat so the sauce is simmering.  Stir in the water, cover and cook for 15 minutes or until the meatballs are done.  Slice the sub rolls and place meatballs inside. Top with mozzarella and pepperoni and place under the broiler on high until the the cheese is melted.
