To cook beans while camping you'd need something like a tiny pressure cooker. I wonder if there are any on the market. It would be a good way to cook beans and rice instead of relying on those awful dehydrated rice-a-roni packets that are full of MSG and other scary stuff.

In addition to instant hummus you can buy chickpea flour from Indian grocers and add it to rice and vegetables to make a meal-in-one-pot. I'm wondering if it's possible to make your own bean-flours using something like a coffee grinder. I'm going to experiment with this at home and try to perfect the high-protein meals-in-one-pot concept.
