How many pounds of pasta salad to feed 100 people?

It's impossible to say exactly how many pounds of pasta salad you'll need for 100 people without knowing more about the event:

* Appetizer or Main Course: Is this the main dish or a side dish? People will eat more if it's the main course.

* Other Food: Are there other dishes? If so, people will eat less pasta salad.

* Portion Size: Do you want to be generous with portions or just provide a small side?

* Appetites: How hungry will your guests be?

Here's a general guideline:

* Appetizer: Plan for about 1/2 cup per person, which translates to roughly 10-12 pounds of pasta salad.

* Main Course: Plan for about 1-1.5 cups per person, which translates to 25-37.5 pounds of pasta salad.

It's always better to err on the side of having too much food than not enough. You can always save leftovers!

Pro Tip: Consider using a pasta salad recipe that can be made ahead of time and easily reheated, like a cold pasta salad with mayo-based dressing.
