People do not eat serving sizes that are recommended any longer. They are used to the oversized meals from restaurants. It used to be 1/4 pound of boneless meat per person. Now that is about the size of a deck of cards. Personally I know very few people who eat that little meat at a meal especially at a holday meal. They tend to indulge. Now if the ham is not the only meat, turkey, meatballs, roast or whatever, I would say yes because they will eat the other too. But if the ham is the only meat I would suggest that you allow more per person. Marlene
