I found http://www.lauraswholesomejunkfood.com/ at a local organic grocery in my town, and fell in love with them.
They come in 7 ounce tubs, with a long shelf life. They can be easily repackaged into a sandwich bag for trail use. The "cookies" are 2 bite size "bite-lettes".
They contain nothing artificial and no preservatives. They taste very good, have fiber and protein, and best of all? They don't get hard in the cold.
I now carry a tub of these with me on all trips. If you want an energy bar without the sawdust-y texture of energy bars, try them! The chocolate chip ones are habit forming.
