How much green beans for 50?

For a serving size of green beans, you typically want to plan on about 1/2 cup per person as a side dish. For 50 people, you would need approximately 25 cups of green beans. This is equivalent to about 12.5 pounds of fresh green beans, assuming they are cooked and served. Adjust the amount based on whether green beans are the main vegetable or part of a larger meal.
