Okay, I'm taking on a BBQ for 350 people. I've never catered anything this big before, but have plenty of help, so I know I'll get through it okay. The menu is steak and ribs. I'll probably end up doing sirloin strips and some cut of pork ribs. Baby back or St Louis...I don't know yet. Just not country style. My problem is I don't know how much to buy for that many people. How many pounds do I buy of each? Please help! Thanks in advance.
