Assuming that this a balanced and portioned meal, an average of 4 oz. by volume would be a good place to start. Some will take more, some less. You should also consider how this 300 breaks down by age, gender and activity level.
I have the same question! I'm probabaly going to just multiply a small recipe; I found out 1 gallon feeds about 25 people.
For 200 people, you'd need around 3 gallons of macaroni salad.
5 pounds of macaroni should be enough to feed 20 people. Depending on appetite each pound can feed between 4 and 5 people.
The standard serving size is 1 cup (of salad) per person, meaning you'd need 75 cups of macaroni salad, which is about 2 ounces of uncooked macaroni per person. This means a 16 ounce package of macaroni can feed about 8 people, meaning you would need 9 boxes. Of course, this is based on if EVERY person ate it, and EVERY person ate 1 cup of the salad. But, keep in mind, if this is on a buffet (where people dip their own), some people will eat a lot more than 1 cup, some will eat a lot less than 1 cup, and others won't eat ANY--making it balance out.
I would make 40 pounds.
Just throw as much as you want in.
It is about $1.50 per 100g at the local Sobeys store in Calgary, Alberta.
How much macaroni and cheese do I need to feed 200 people for one meal
Well it does matter if they are kids because if they are kids then they would eat less but if they were adults they would eat moer. If you plan on giving a equal amount then there moght be a chance that you can feed that much to them :)
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.
I would give about 4 ounces each - about 38 pounds
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.
You need 12 lbs of mixed lettuce and about 1 gallon of dressing(more if creamy).
