Speaking of traditional food:
I generally prefer to have canned food with me and "sucuk (sujuk)"
some sort of bacon which can be eaten both raw or cooked. It has good deal of fat and meat in it with some spices. It lasts a long while.
I also like to have canned beans and canned tuna fish. All these can be eaten without needing to built a fire and even when you are moving.
For bread we have some sort of a roll type bread like the mexican ones. They last for long and do not take much space to keep.
Another thing is Bulgur. Bulgur is a quick-cooking form of whole wheat that has been cleaned, parboiled, dried, ground into particles and sifted into distinct sizes.It is not cracked wheat. You can use it instead of rice and it has a higher nutritional value.
Another favorite of mine is instant tomato soup mixed with "tarhana".Tarhana is made of a mixture of salt, wheat flour,low fat yogurt, skim milk powder, pepper and tomato paste, vegetable oil, red pepper powder, yeast. Than it is dried and ground. It lasts a very long while.
I also always have bitter chocolate with me. Lasts very long.
Well I come from migrant ancestors <img src="images/graemlins/smile.gif" alt="" /> Our kitchen has many practical food to carry with you on the field.
Spending some time with locals and villagers on the country side I have changed much of my food carry. I have tried MRE and British rations and for me the taste is not very good. And I also think they are heavy. Besides when I eat whole that lot I need to spend a lot of time behind the bushes <img src="images/graemlins/smile.gif" alt="" />
