I think I have everything but not sure on how much fruit and veggies to buy

crab dip-3 gallons
crackers-12 pounds (probably some left)
cheese dip-3 gallons
chips-1 pound per 12
fruit tray- use the fruit tray page; 1 1/2 times the deluxe tropical tray, or equivalent, would be about right.
veggie tray- use veggie tray page, do for about 150, or consider doing the classic relish tray x2 instead
dip- Ranch, discussed on the veggie tray page
cheese tray- about 18-20 pounds, some could be logs or balls, use crackers above

BBQ Pulled Pork-about 40 pounds
yeast rolls-1.5 per person if large, or 2 smaller
BBQ sausages-about 40 pounds
You also need something to serve as and entree for non-pork/ non-meat eaters- with 200 guests there will be some. Field roast is the brand name of an excellent vegetarian sausage- do about 18
jambalaya- about 10 gallons
corn- 44 pounds
green beans-44 pounds
pasta salad- 12 pounds dry pasta plus add ins. Many recipes on this site. Make it meatless.
For BBQ pork, consider adding 5 gallons cole slaw

punch- with appetizers, 10 gallons
tea-12 gallons, 1/3 unsweetened
water - 2 bottles per person
ice, about 1/2 pound per person
