Determining Quantity???

[Esther]

I need to feed approx 125 people.

Approx 90 servings of Chicken Spaghetti and 35 servings of regular spaghetti.

I think 9 -9 x 12 sheet cakes should cover the desserts.

The bread we are taking hot dog buns and cutting into 4 long ways and dipping in butter with Lawley's garlic salt to make bread sticks. There are 8 buns in a package, which would make 32 pieces. Figure serving at least 2 per person. So I am guessing 10 packs should be enough with a couple extra's.

Someone suggested 10 lbs of hamburger meat should be enough for the regular spaghetti. I usually use about 2 cans of tomato sauce per 1 lb of hamburger meat.

Now for the hard part. I tested this recipe and it will serve about 25-30 people depending on the size of serving you give.

2 - cans rotel
1-whole chicken
2 cans cream of chicken soup
2 cans cream of mushroom soup
1-14oz chicken broth
1-lb Velveeta cheese
1 lb spaghetti
Salt
Pepper
Onion salt

I don't know whether to make 3 or 4 of this recipe. I hate to run short. And I don't know how much the servers will actually give.

Any suggestions? Anyone done this before?

Thanks
