Make at least 100 croissant. The rest of the menu is carb heavy, so not all ladies will eat 2.

Each cup of filling will make about 6 sandwiches.

Usually, 1 pound of boneless chicken meat makes just short of 4 cups of salad- about 1 cup mayo, 1 cup celery, 1/4 cup chopped fresh parsley. If you add grapes, cut them, add about 1/2 cup and reduce celery.

About 50 croissants and 24 to 30 turkey sandwiches. Consider a few egg salad or pimento cheese for any vegetarians.

A 3 pound tub is usually 12 half cup scoops, but I strongly recommend buying one and checking. Weights vary depending on amount of dressing, types of add-ins.

Check the price of boneless chicken thigh meat. It is moister and more "chickeny" than breast meat.

The simplest "chicken salad", which used to win prizes in the little LA deli I worked in, was
whole turkey, baked, boned, skinned and chopped, fairly fine
equal volume fine chopped celery, including leaves
equal volume fine chopped fresh parsley
finest lemon and olive oil mayo (we paid $8 per gallon when Hellman's premium was $3 per gallon)
That's all.

When we had to switch to whole chickens due to a truth in labeling regulation change, it was not quite as popular.

For pasta, see the spaghetti page, which tells the difference for pasta salad vs. side or main dish pasta. Do 2/3 the amount for 100 and you will have plenty.

You might consider just doing the ham salad; more chewable. Also, maybe add some pimento cheese or a cream cheese spread? Here is an approximation

turkey, 80
10 sandwiches per pound= 8 pounds, deli sliced; maybe cranberry jelly?
ham salad, 50, 1 cup per 6, about 9 cups
chicken salad, 50, 1 cup per 6, about 9 cups
pimento cheese or cream cheese spread, 20 (if not, spread around among the others)8 per pint, about 3 pints

Consider doing a marinated veg tray instead of a crunchy veg tray, again, chew factor. Here is an on site link:

If you are making it, for crackers be sure the veggies and add ins are fine dice and skip raw onion.

There are two whole sections on tea party sandwiches on this site with lots of hints. About keeping fresh, preventing sogginess, etc.

Consider adding a fruit tray selection.

The place I am looking to buy chicken salad from sells in pints and quarts - how many cups do I need to make 30 mini croissant sandwiches?

Make at least 100 croissant. If the rest of the menu is carb heavy, not all ladies will eat 2.

Each cup of filling will make about 6 sandwiches.

Usually, 1 pound of boneless chicken meat makes 3+ cups of salad- about 1 cup mayo, 1 cup celery, 1/4 cup chopped fresh parsley. If you add grapes, cut them, add about 1/2 cup and reduce celery. 5 pounds boneless skinless is at least 10 cups- can make as much as 16, depending on additions.

What do I need for 90 mini croissants VS regular size?

I made 7 lbs. of cooked chicken for 60-70 mini croissants and had lots left over.

Just need to know if the weights listed are before or after cooking.
