Have decided on amount of meat for 150 for my daughters open house but am not sure about sides. I will do pulled pork sammies, brisket and chicken wings. I have the amounts figured out (I hope) but I do not know how much cole slaw, potato salad, and baked beans I will need. Thanks in advance. (my daughter will only let me cook, but will let me buy the slaw and potato salad if her aunt can bring her (should be famous) baked beans). As tight as things are we do not want to over-buy.
