I would do 8.75 pounds of greens if it is for appetizer/side. I figure 3.5oz of greens per person if it’s an even mix of men and women. If it’s all women I go more, all men I go less. It never fails when I cater pizza and salad that the women eat mostly salad and the men eat mostly pizza. These numbers also include a decent cushion if you’re charging per person.
For forty people, beyond the greens, my catering salad would also have 10oz black olive, 10oz tomato, 10oz mozzarella cheese, 70 small pepperoni slices and 60 fluid ounce of dressing. It’s way too much dressing, but people load it on and I don’t want them to run out.
I charge $1.49 per person for this salad if they’re also buying mains from me. My menu price would be $1.89 per person if they’re not buying anything else.
If you don’t normally do salads you may not know this, but lettuce prices and quality stink right now. I’m only getting about half the yield from a case as two months ago and the price is up 40%.
Edited to add: The per person amount and the price come down if the party is dine-in where I can have more salad ready to serve if needed… no cushion necessary. I think you’re a DELCO so that probably doesn’t apply.
