We're staying offsit and cooking meals primarily because of allergies. I really like good food, but I don't really want to cook a lot on my vacation, so we're rotating cooking duties and using a lot of convenience foods. We'll stop at Costco on our first full day while the kids take an afternoon break. The plan is:
We'll have a veggie/dip tray from costco to augment meals along with some salad in a bag and an assortment of fruit
Pad Thai (from a kit, just add shrimp, egg, chopped peanuts, sriracha, veggies)
Pizza
stuff in peanut sauce (steamed veggies, more shrimp or precooked chicken strips, peanut sauce over rice made in the rice cooker)
Mexican night (carnitas from costco, tortillas, salsa, can of refried beans, rice, cheese, salad - everyone assembles what they want)
Pasta with sauce (I'm watching for good looking pre-cooked sausages to brown up for those who eat meat, but we'll probably just add chopped carnitas or precooked chicken strips)
Indian and Thai food from packets (Trader Joe's makes great shelf-stable thai and indian food, I'll take enough packets down for a couple of dinners)
We'll rotate through that assortment twice and have a few dinners of whatever people want to scrounge up for themselves. I think that my sister and I are going to have sushi on property one night too. Not a lot of repetition, not a lot of ingredients, and none of it takes longer to cook than boiling some pasta. The most intensive one is pad thai - but pad thai is my favorite on the menu, so we're having it anyway. :>
Breakfasts will be an assortment of freezer waffles, muffins, bagels, donuts, cereal, fruit, eggs, yogurt, probably some pre-cooked breakfast meat (precooked ham, bacon or sausage).
Lunches for the kids will mostly be mac and cheese from frozen, hot dogs, hard boiled eggs, yogurt, veggie sticks, fruit. And for the adults probably sandwiches, fruit, veg, salad, leftovers from the night before, etc. We tend to eat small lunches with larger breakfasts and a hearty early dinner around 4pm before we go back to the parks.
