We rented a house in Cape Cod last year (8 adults, 1 child) and cooked almost every meal there, at least breakfast and dinner. Lunch was more fluid, depending on whether we were in/out, had leftovers, etc. For dinners, we grilled several nights...burgers and dogs one night, chicken another, steak another. Someone brought homemade meatballs they had made and frozen, and we had pasta w/sauce and meatballs, big salad, and garlic bread one night. I braised a pork shoulder before vacation, shredded that, froze it, and had pulled pork one night with baked beans and corn on the cob.
For breakfast, we just brought a variety-- a couple dozen eggs, bread for toasting, lots of fresh fruit that could double as snacks, a few kinds of cereal, and yogurt. The two things we didn't bring enough of and had to replenish a few times were drinks (both adult and non-alcoholic) and some snacks.
