How many heads for lettuce to fix tossed salad 100 people?

To prepare a tossed salad for 100 people, you will need approximately 10 heads of lettuce. This may vary depending on the desired portion size and the types of lettuce used. For instance, if using romaine lettuce, which has larger leaves, you may need slightly fewer heads. On the other hand, if using a mix of delicate lettuces, such as baby arugula or butter lettuce, you may need a few more heads. Additionally, consider adjusting the amount of lettuce based on the other ingredients in your salad. For a salad with substantial toppings like grilled chicken or pasta, you may opt for fewer lettuce heads to balance the overall composition of the dish.
