You sound a lot like us. We eat cereal for breakfast, put sandwiches, crisps and drink in a coldbox in the car, then in the middle of the day we find it rather peaceful to go back to the car have the engine running and the air conditioning going and eat lunch. You will however need a good supply of cold packs as the temprature in the car can get very high. For your evening meal why not try chicken tenders, potato wedges and a bag of salad, all from Wal Mart which we take back and have at the villa with a glass of wine, if we eat eat then hubby can't drink!
