Mozzarella-Stuffed Meatballs

1 egg, lightly beaten
1/4 cup prepared Italian salad dressing
1 1/2 cups cubed bread
2 Tbsp minced fresh parsley
2 garlic cloves, minced
1/2 tsp dried oregano
1/2 tsp pepper
1/4 tsp salt
1/2 lb ground pork
1/2 lb ground sirloin
3 oz fresh mozzarella cheese
2 Tbsp vegetable oil
1 jar (26 oz) marinara sauce
Hot cooked pasta

In a large bowl, combine the first eight ingredients.  Crumble pork and beef over mixture; mix well.  Cut mozzarella into eighteen 1/2" cubes.  Divide meat mixture into 18 portions; shape each around a cheese cube.

In a large skillet, cook meatballs in oil in batches until no pink remains; drain.  In a large saucepan, heat marinara sauce; add meatballs and heat through.  Serve over pasta.
