Philly Meatball Sandwiches

One of my favorite quick versions of a classic sandwich.

Difficulty level: Easy
Total Time: Less than 30 minutes

1 pkg cooked meatballs
1 tablespoon oil
1 onion, chopped
1 green pepper, sliced into strips
4 French or Hoagie Rolls
4 oz. shredded mozzerella cheese*

In a large skillet, saute onion and green pepper in oil. Meanwhile, heat meatballs in microwave until hot.  When vegetables are almost tender, add meatballs to skillet.  Spread cheese over mixture and cover.  Heat for 2 minutes, then let stand until cheese melts. Serve on Rolls.

*You can substitute cheese whiz for a more authentic Philly if desired.
