there is a raw food version of this but you could add cubed chicken or tuna too.you just find a large cucumber and hollow it out with a spoon, thin knife or grapefruit knife and then fill it with chicken or tuna salad or whatever and you have a portable sandwich.i just cover it with foil or saran wrap and peel away.i have also filled those small green and red peppers that come in a bag=which works great too.
