Shared or free is good...
Mostly I eat as if I were in the cabin, minus baked stuff.
If I resort to MRE's- I will likely starve instead.
Lots of beans, rice, tuna, beef, eggs, fresh and dried fruit, nuts, yogurt, honey, bread, cheese. Some canned veggies( corn, spinach, tomato,) for soups or fratatta's (sp?) onions, potato's, leeks
fresh or frozen fish, canned oysters, clams or shrimp, crackers, usually have popcorn and trail mix for snacking.
