I've had several reunions and graduation party that i have cooked for , but it was meat only they had the sides . How do you figure how much of side dishes I will need if I cook for a party an do meat and sides ? Like baked beans , coleslaw, potatoe salad I have recipes for them but don't know how much to fix . Is there a general guide line for say 25 people then just add to it ?so many lbs fir this number of people ? Any help will be greatly appreciated
