Soak walnuts overnight in two cups of water, about 8 hours.
Drain and combine the filling ingredients in a food processor. Process until the mixture is creamy.
With a 3 ½" round cutter, cut 12 rounds from crusts and re-roll if necessary.
Preheat oven to 375F.
Place the pastry rounds in each cup and prick the bottom of the cup 2-3 times with a fork.
Spoon about 1 ⅓ tablespoon of the walnut filling into each cup.
Roll strip of zucchini or carrot into a spiral and place in the center of each cup, then surround it with a few strips of carrots and eggplant until a spiral pattern forms in the cup.
Drizzle or spray olive oil over all and then season the vegetables with sprinkles of salt and pepper.
Bake for 35 to 38 minutes or until the crust is browned.
