Just bring your favorite skillet from home and do stir fries.

You can buy pre-cooked bacon that does not need refrigeration (though I do not know its requirements once the package is opened). If you buy ice every day you can keep meats chilled well enough.

If you are doing any communal cooking with your group you can plan more easily for no leftovers. A pasta dish made with packaged smoked salmon would be good, and use the rest of the salmon with scrambled eggs in the morning.
