Ramen and tuna is ok. Ramen and chicken is better. When I was forced to eat outside by my Uncle Sam, I carried Ramen, cocoa, canned chicken and canned tuna. I'd go through the MREs and take out what was semi edible or stuff I could mess with and make edible. The difference in weight usually was in my favor - dropping most of the MRE off and replacing it with lighter stuff.

I also carried spices, like salt, pepper, garlic powder, onion flakes and tobasco.

You got to eat, but you don't have to eat bland crap unless you want to.
