For some, if not most, the concept of having a mashed potato sandwich may seem disturbing. However, if you find yourself wondering whether you are loosing your mind, you probably have never tasted one. They are delicious! So overcome your inhibitions, and make a mashed potato sandwich next time you have a little leftover. For this one I felt like adding flax seeds and ham. Since I want the ‘crunch’, I toasted half a ciabatta roll, and added fried onions on top for good measure. For a little hint of sourness, sweet dill pickles always does the trick, and a sprinkled of my newfound love, Dukkah, seals the deal.
