I discovered one great staple as a result of bicycle touring/camping.
I buy some whole wheat coucous and some dehydrated/curried green pea or black bean soup at the health food store. I boil water and pour over a 50-50 mixture of this seasoned with curry powder and salt.
This is a great on-the-road dish, but it is also a nearly instant and energy-free way to prepare a dish on a hot summer's evening.
Great addition to some left-overs or perhaps as a side dish with an omelette.
