We are having a September wedding in 2016 with probably around 150 guests. We are planning on roasting a pig, having bbq chicken (we have a group that will do it for free, we just have to provide the meat), and making homemade sides (i.e. baked mac and cheese, baked beans, pasta salad, coleslaw, etc.). Has anyone had experience with this? How much meat and sides did you buy?? How long does it take to warm up on the sides in the chafting dishes?
