I'm looking to likely do a some kind of crostini, a seasonal roasted veg, a chicken dish, a pasta salad, a cake + some cookies. Want to make sure it is "enough!" and also I will be out from 10-12:30. Wondering if I should refrigerate overnight and take things out to temper before I leave the house or upon return. Any advice from frequent hosts or go-to recipes would be great. All omnivores, 3 teens, a handful of hungry men, but it will also be early in the day...Thanks in advance!
