For 200 people, you'd need around 3 gallons of macaroni salad.
Only if you want to
You need 12 lbs of mixed lettuce and about 1 gallon of dressing(more if creamy).
It depends if you only serve pasta salad or something else with it. When you serve only the pasta salad - I would use 6 packages ( 6 pounds ) of pasta, 6 tin peas, 24 tomatoes, 8 onions, 2 pounds ham, 6 tin corn, 3 red pepper. If you want to serve this to a bbq - I would recommend a quarter of the recipe above.
You would need about 1/4 a pound of chicken salad per person. That will be 17.5 pounds of chicken salad for 70 people.
How much will you serve one person x how many people are expected = how much you should make. For instance, if you will give each person 1 cup of green salad and you are expecting 50 guests, the formula would be 1 x 50 = 50. You'll need 50 cups of salad.
You would need 3 average lettuce.
Yes, you can, but you will need to keep it chilled until time to serve.
really that depends on who you're feeding . 9 men wouldn't eat what 9 ladies etc. but if say 1/4 to 1/2 lb per person
Generally speaking, 5 lbs of potato salad will fee 30 people. 12 people would be a little over half of that, so around 2.5 lbs of potato salad.
Depending on how much cucumber you'd like in your salad, you can use anywhere from 8 to 15 cucumbers for a salad serving 30.
How much you need to increase the measurements of a taco salad to feed 75 people depends on how many people the original recipe was for. If the original recipe was for 5 people, you would need to multiply all of the ingredients by 15.
