Chips and dips, veggie and fruit trays, anything bbq, lol, corn on the cob, watermelon, potato salad, macaroni salad, ummm thats all i can think of at the moment lol. You vould make it potluck style too if you wanted, and everyone bring something, or just provide all the sides and have everyone bring their own meat to throw on the bbq...you could just have ppl bring their own drinks too, but i remember you saying earlier ur husband is teying to avoid alcohol, so if u think ppl may bring it, just provide drinks...coolers of pop water etc...hope that helps :)
Snacks hmm Idk I would just have a bbq and u cant go wrong with beer
Fruit, sandwiches, pasta salads, cracker and cheese trays, various dips
