If this were a family gathering I would suggest pound raw boneless beef per 3, plus 1/2 pound raw whole turkey per person plus 1 cabbage roll plus 10% if large, or 2 per person if small, plus 3 ounces pierogie. When you have a lot of choices people tend to eat more and to take some of each. For the rest see planning and shopping for a large community meal, at the top of Big Pots. Count this as 1 2/3 hundreds.
