@Setanta,
No, I usually make one with the Mozamelt and the other I eat with liberal dosages ofTABASCO.
The meat-a-balls are a bit sweet and the gravy is chunky. SO, the Tabasco is a natural (for me cause I love spicy anything)
Mrs F did put Mozarellla on the other one. We take 2 big rolls and doctor up the sammiches and cut em in half. Twofer her and teofer me.
