Recipe given from close friends w/ Italian background.
2 frozen loaves of Rhodes bread (white), or pizza dough recipe (enough for 2) or pre-made dough you can buy at the store
10 thin slices of VA Baked ham (or equivalent)
10 thin slices of hard salami
10 thin slices of provolone cheese
10 thin slices of mozzarella cheese
Roll each loaf or each pizza dough out to form long rectangle (usually the length of a cookie sheet) and wide enough to fold top over ingredients (usually ends up the width of a loaf of french bread). Spread thin layer of mustard on bottom half of dough and sprinkle oregano over mustard. Lay down a layer of 5 pieces of VA ham over mustard/oregano, then provolone, then hard salami, followed by mozzarella. Fold top over and roll bottom dough over top to form a lip and pinch shut. Spread thin layer of butter on top and place on lightly greased cookie sheet. Bake at 375 degrees for approx 15 min or until lightly golden brown. Remove from oven and cut width wise (usually can get approx 6 good size pieces). Recipe makes 2 long loaves of Stromboli.
I've added green peppers, onions, and olives to mine before. You can add whatever you like or just keep to original recipe, all is good. Marinara is a good dipping sauce also. Enjoy.
