300 pieces of roasted chicken- 200 plenty
210 hot and mild sausages peppers and onions- do about 2/3 sweet/mild and label them or stick a bunch of obviously hot raw peppers on top of the hot ones for decoration
Do 1 crock pot of vegetarian sausages, my favorite is Field Roast
6 gallons baked beans- OK, maybe make 1 gallon meatless in a crock pot for any non pork eaters, then the rest will fit in a standard electric roaster
30lbs cole slaw, I usually do 40-45 pounds for 200, especially with no green salad
6 gallons potato salad, I usually do 4 gallons per 100
Rolls- 2 per person, get good ones, 5 pounds butter for 200
mustard, about 3 quarts, some spicy types

Charcuterie table
Six heavy veggie trays with two dips, OK
8 lbs cubed cheeses, maybe consider increasing to 10-12 and adding 3 pound block cream cheese with preserves, or a similar amount cheese log/spread
12 sleeves assort crackers- 10 pounds
4 lbs mixed nuts, usually 6 pounds per 100
3 lb olives, usually 3-4 quarts per 100
2 lbs pickles artichokes,mushrooms
At least 2 gallons, and maybe add a #10 of roasted peppers?
5 lbs shaved meats? Consider switch to very thin sliced summer sausage, pepperoni or other small hard sausage. People take less. 1 ounce per person is about 12 pounds.
5lb red 5 lb white grapes, maybe add 8 quarts strawberries? Good this time of year and often on sale.
