I am prepping early but we are having all our family here for Thanksgiving, and even though everyone will be helping out I just dont know what to tell them when it comes to how much each person should make. so heres the run down: high balling at 40 people, but probably around 30 but I would like to keep the number high. we are having pre cooked turkey breast that are about 4lbs each and a honey spiral ham which are about 10-12 lbs each. how much ham and turkey will we need? then there are the sides: mashed potatoes gravy corn bread rolls sweet potato casserole stuffing cranberry sauce green beans carrots mac and cheese streamed veggies and I cant think of anything else, but im a planner and I like to have this stuff figured out in advanced. Everyone in my family wants to prepare a dish but like I said I have no idea what to tell them when they ask how much of each they should make.
