This is a Turkey Meatball dinner idea. Reheat meatballs in spaghetti sauce on the stove top. Toast the roll a little so it doesn't get too soggy when you add the meatballs and sauce. Place meatballs & sauce on the roll. Top with mozzarella cheese. Place sandwich open face on a cookie sheet to toast the bread and melt the cheese, low broil 3-5 mins. It never fails that the kids practices are right in the middle of dinner time. I feed the kids before practice and often I wait till after their practice to eat my dinner at which point it's 8pm and I'm beyond Starving! This is not good thing!
So along with napkins I wrap this sub in foil and take it to the field!
