Cut Cuban bread to desired size, common size is 7 inches. Next, slice open the bread down the middle. On the topside of the bread spread 1-ounce of mustard, evenly across. Then place 4 pickles on top of the mustard. You then place 1 slice of Swiss cheese on top of the pickles. Slice ham to desired thickness, recommended size is 1 1/2 ounces per slice, the thinner the better. Now fold each slice of ham in half and place evenly on bottom of bread. On top of the ham, place slices of roast pork, 1 1/2 ounces per slice. You then join both halves of the sandwich. You are now ready to grill your Cuban sandwich.
