This is important, because while you can easily gauge the number of sausages (we usually plan one sausage per person), gauging the vegetables is much harder. u003cbr/u003eu003cbr/u003eI suggest allowing 2-3 cups of raw vegetables per person, because the amount will reduce significantly when it cooks.u003cbr/u003eu003cbr/u003eWhen I make this for my family of four, I cut up 4 peppers, 3 large onions and 16 oz of mushrooms. This gives us plenty of veggies for dinner, and hopefully some leftover for lunch the next day.
