I don't eat much, but I definitely still snack during events. We lay out stuff like cheese, bread, meat and some fruit out around lunchtime, so once everyone's had a bit, there's always plenty of cheese, meat and apples to snack on.
Sometime's there's even bread left, which means extra bread and cheese.
Dinner is usually stew of some kind, but only with ingredients we'd have had available in northern europe. No taters, precious.
