I am making meatballs this weekend for my boyfriends Christmas party. There are going to be between 15-20 people attending. I need to know how much ground beef to buy. Is 1lb not enough? I made them last year but I totally forget how much I used...also, how many eggs and how much bread crumbs would I use per lb of meat? I did a search and found some great meatball recipes that I may use...Thanks!
