How Much Food do I Need to Feed 100 People?

This depends on what type of food you will be serving. For example, for 100 people, each person would consume one hot dog, so you would need 100 hot dogs. For roasted meats, expect your guest to consume about one pound. The meat will shrink also, so you should expect to purchase about 50 pounds of raw meat. For salads, you would need about 12 to 15 heads of lettuce.
