I am new to throwing cocktail parties, please help everyone. I’m having 8 people over next Friday and I am serving heavy hor d’oeuvres. I plan to have: 5 different Italian meats and 5 different cheeses a cold antipasti platter of all the usual veggies a chaffing dish of mini meatballs in marinara sauce deep dish Pizza squares rolled Stromboli, sliced Spinach and Fontina Fritatta squares a tray of mini Cannolis with coffee Now, my urgent question is this: How much of the meats do I buy? I googled and the answer was 3 ounces for each person, is that really going to cut it? At about $30 per pound, I don’t want too much waste. And then what about the cheeses? How much of those should I get?
