Each large, full-size meal contains 6 servings and will typically feed between 4 and 6 people depending on the item and desired portions of your family (adults tend to be accustomed to larger portions than kids). Remember, you will also be serving side dishes and other items to round out your meal, and it may be helpful to consider salads and other accompaniments when you are planning.
Small portions will feed 2 - 3 people.
