We're going to England to walk around the Cotswolds. I'm not sure what to take on the plane or while hiking. I have no idea what's available in stores (assuming there are grocery stores in the villages we're visiting) so I thought I'd try to pack some stuff. But I'm not sure what to pack. While nuts and seeds are healthy and packable, I have a hard time keeping it to a handful, unfortunately. Any low-calorie, non-refrigerated, energy bar-type recipes? What kind of food have you taken on a long plane ride and while hiking?
Thank you!
