All great ideas. Don't forget the roasted chickens you can pick up at local grocery stores. Their salad bars will give you a nice meal with that chicken.
You can freeze lasagnes and other casseroles. Or you can buy a lasagne/other casseroles in the local grocery freezer section to make that night. We hit farm stands for fresh fruit and veg too. Part of the adventure is eating local and finding local specialties in shops. We found a terrific meat market in one town. On the way back to camp we found fresh corn and tomatoes at the local farm stand. We ate too well that night :w
