According to the US Dry Bean Council, dried beans provide an excellent source of protein, iron, magnesium and zinc; are high in fiber known to reduce cholesterol levels, and provide a good source of antioxidants. Beans are relatively inexpensive, provide a nourishing and filling meal and require minimal supervision while cooking, making them ideal for large gatherings like barbeques and potluck dinners.

Things You'll Need

Determine the amount of cooked beans expected to be consumed by each member. One half cup is considered a serving, but guests may eat more or less depending on whether beans are the main attraction or served as a side dish. As a rule, allow between 1/2 and 1 cup per person.

Cook 10 to 15 pounds of dried beans to feed 100 people. According to the California Foundation for Agriculture in the Classroom, a one-pound bag of dried beans provides 10 servings of 1/2 cup.

Prepare 10 pounds of dried beans if several other foods will be offered at the same meal. If beans are the main course, you may need 15 pounds to provide 3/4 cup per person.
