When serving boneless meat, including stew, roasts, chops or chicken, plan on 1/4 to 1/3 pounds of meat per person. The weight of meat per person is determined when the meat has not yet been cooked.
It is recommended for holiday gatherings that the amount of meat per person be slightly increased to allow for second helpings. Likewise, the amount of meat per person can be reduced if there will be a lot of side dish options offered.
