a while ago i discovered that tuna now comes in 3 ounce vacuum sealed pouches. the water is already drained from the pouch. they are like a dollar a piece at the grocery store.
its lightweight, takes up little room and is rich in protein and sodium. theoretically it cant spoil in the pouch and could be brought on rides in very hot conditions.
would this be a good riding food or would something with carbohydrates be better?
