I made these for a large group and they were a huge hit! Here's what I used: 3 dozen dinner rolls (baked 6 together, kind of like Hawaiian rolls), 32 oz. olive mix, one pound of ham, and 1/2 pound of turkey, 1 pack of turkey pepperoni, 18 slices of swiss, 12 slices of provolone. The number of slices will depend on how big each slice is. Leaving the rolls in tact, cut the top off and remove top layer. Spread olive mix on the bottom bun, then add meats & cheeses over the whole thing , then another tablespoon of olive mix on on each, and put the tops back on. Wrap in foil. I took 6 big foil pouches (of 6 sandwiches each) to the meeting place and baked them when I got there. They were done in 9 minutes. Then, slice between the buns to separate and serve.
