Take a succulent Mejdool date (see below in pictures). Cut part way through, remove the stone. Replace stone with one or two halves of a pecan nut. Press it closed and wrap in grease proof paper like a sweet. Snip one end, to make it easier to unwrap and eat while riding. Fill yer jersey pockets, but go easy there - each one has about 80 Calories (if you use two pecan halves).
