Meatball sammiches

1 pound ground beef

3 tsp onion powder

1 tsp garlic salt

2 tsp garlic powder

1 egg

1 cup italian breadcrumbs

1 jar tomato sauce

1 pound mozzarella cheese sliced

4-5 sandwich rolls

Preheat oven to 325.  Line a baking dish with foil and spray with cooking spray. Combine first six ingredients.  Roll into 1.5 inch meatballs.  Bake in oven for 8 minutes.  While they are baking heat sauce in large sauce pan.  Flip meatballs and bake for another 8 minutes.  Place meatballs in sauce and simmer for 2 minutes.  Slice bread in half without cutting all the way through.  Line bottom of bread with mozzarella cheese.  Top with 3-4 meatballs and cover with more cheese.  Place under broiler on high for about 2 minutes.  WATCH IT SO IT DOESN'T BURN.  I served it with a side of sauce for dipping.  

Enjoy trying to fit it into your mouth!
