I'm toying with the idea of making my own bbq pulled chicken rather than buying it prepared at the local bbq place due to the high cost $10.99 per pound w/o buns. Not sure how many sandwiches a lb of pulled chicken would serve? Also given that I will have a variety of side dishes how many lbs should I have of each side?
Also if I wanted to serve a sweets table with a variety of cookies, bars,cakes, what quanities should I prepare?

thanks in advance!

bbq pulled chicken sandwiches (45 servings), you need about 65, which is 13-15 pounds ready to serve; 1 pound whole chicken or chicken quarters makes 1 cup of meat, about 8 ounces. 1 pound boneless makes 2 cups. Pulled chicken is about 1/4 sauce, so you need about 11 pounds of meat. It is not hard to make.
a veggie bbq chicken option (30servings),

coleslaw, 2 1/2 gallons, easy to make at home, even with the pre-shredded cabbage
pasta salad, 6 pounds dry pasta plus add-ins, very easy and economical to make ahead, good recipes for 100 on this site

veggie trays,use the veggie tray page, 2-3 ounces (about 6 bites) per person
hummus, 1/4 cup per person, olive oil and sumac or sweet paprika to garnish
You need chips, pita chips, or pita, about 6 pounds

baked beans, scant 3 gallons

I will definitely donate!
