Preheat oven to 400F. Grease a cookie sheet or line with parchment paper and set aside. Cut zucchini into sticks 1/2-inch thick and set aside. Grind bread crumbs using a mortar and pestle to a fine consistency. Mix crumbs with vegan Parmesan, garlic powder and a few dashes of salt and pepper. Place crumb mixture into a shallow bowl. Pour non-dairy milk into another bowl. Dip sticks into non-dairy milk and then press all sides into the crumbs mixture. Transfer to a cookie sheet, spray with cooking spray (optional) and bake 15-20 minutes, until the breading is golden brown and zucchini is tender.
