Per personally, I bring a bunch fresh veggies and herbs such as mustard, bitter melon, peppers, mint, lemon grass, ginger, garlic, scallion, cilantro, banana leaves, lime/lemon, bread and round egg plant as well as rice grains (both jasmine and sweet). Obviously salt and drinking/cooking water are a given. And no meat of any kind because I can get fresh killed meat at the hunting grounds...
The veggies and herbs I bring looks similar to the ones in the photo below:
