Wrap the beets individually in aluminum foil. Bake for 1 hour, until a knife is easily inserted into the beet. Let them cool, and peel the skin off. Use a mandolin to slice the beets about 1/4 inch thick. Use a biscuit cutter to cut out beet slice circles.
Mix the sage and parsley with the goat cheese. Add the honey and season with freshly cracked pepper and salt to taste. Put dollops of goat cheese in between layers of sliced beet, until you get five slices of beet per napoleon. Serve with the chopped pistachios on top and watercress on the plate. Enjoy!
