How many heads of romaine lettuce for 22 people?

For a gathering of 22 people, you would typically need about 2 to 3 heads of romaine lettuce, depending on the size of the heads and how the lettuce will be served (as a salad or as part of a larger dish). If each person is expected to have a generous serving, aim for 3 heads. If it’s a side salad or part of a mixed dish, 2 heads should suffice. Always consider the appetite of your guests and any other dishes being served.
