The menu for my son's party last year is below. We had people trickle in over a few hours. The hot items were kept warm in the buffet line with sterno.
- Assorted chicken wings
- Veggie crudite with dip
- Fruit, cheese and cracker trays
- Chips and salsa, chips and dip
- Baked ham with pineapple (I baked it the day before, sliced it, and put it in a pan over a chafing dish and sterno to keep warm)
- Ziti, chicken and broccoli from a local restaurant
- Meatballs in sauce with rolls and Provolone on the side
- Roasted potatoes
- Roasted veggies
- Salad
- Rosemary and sea salt dinner rolls
- Assorted desserts
- First Communion cake
For other large parties I've done a deli platter or two, a tray of "salad" sandwiches (tuna, seafood, chicken, ham), a pan of baked ziti or a lasagne, super-size subs cut into small slices, calzones or a crock pot of pulled pork.
What helped me most last year was that I planned a timeline down the minute of what needed to be done when. I was able to print and post this on my fridge and as my useful family members wandered in and asked what to do, I pointed them to the list and asked that they take the next item.
