I am hosting a college graduation party for my daughter in two months. Although I have the menu figured out, I have no idea of how much of everything to prepare. That's where I need expert help, please. This is going to a cold, fork buffet (pretty much). The menu is: Sliced eye roast with horseradish mayo Sliced turkey breast with cranberry mayo Sliced ham with some sort of mustard concoction All above served with petite dinner rolls Roasted shrimp and orzo salad (Ina's recipe) Chicken salad veronique (also Ina's) Caponata Tortellini salad with pesto, artichoke hearts, sundried tomatoes and olives Asparagus with some sort of orange dressing Grape tomato and mozarella salad Deviled eggs (maybe) Fruit salad Mini cannolis and pastries (which I'm buying) So that's it. But how in the world do I figure out how much of everything to prepare? Any and all help, comments, critiques or general offerings will be greatly appreciated. Thanks so much, Kathy
