You can't get buch easier than this recipe.
You can even use canned or frozen bread dough if you do not want to make your own.
1 lb bread dough (half of this link's recipe)
1/2 lb salami
1/2 lb ham
1/2 pkg pepperoni
1/2 lb grated cheese
1/4 cup grated parm cheese
Roll out dough in rectangle shape.
Layer meats in row down the long side.
Add cheese and sprinkle seasoning on top.
Roll up dough into log shape, sealing edges.
Bake at 375 for 25-30 minutes.
Wait about 5 minutes before cutting. Serve with sauce for dipping.
That's it! I sometimes add turkey or pastrami as well, really whatever I have on hand.
