I'm making/buying the food for my reception (instead of having it catered) but I don't know how much food to get! We want to have cheese, crackers, veggies and dip for appetizers and tossed salad, cold pasta salas and lasagna for lunch. We have 85 people (if everyone comes) and 1 is a vegetarian (so I think I only need to have one pan of vegetarian lasagna). What do you think? I don't want to have a ton of leftovers but I don't want to run out either...Thanks!
