I'm going on a mini family vacation with my parents, siblings and their families in July. We are renting a house on a lake from Thursday night until Sunday morning. Our usual deal is that my parents pay for the house and the kids (me and my brothers) pay for the food. There will be a total of 19 people (10 adults and 9 kids ranging from 7 months to 14) so we won't go out for dinner. Peapod will deliver so we thought it best to just buy all of our groceries and have them delivered. What would you plan for meals? The one caveat is that my niece is DF and GF so there would need to be easy variations to accommodate her.

I know we'll grill out some burgers and dogs at least one day either for lunch or dinner. One night will be taco night as I'm planning on making pork and chicken in advance and freezing. I'll bring my crockpots to reheat. Keep in mind that I don't know how well stocked the kitchen will be.

What else would you suggest for easy breakfasts, lunches, dinners, and snacks?
