A layered casserole with thinly sliced heirloom apples and sweet potatoes.
Peel the sweet potato and slice it in a mandolin or food processor into very thin (1/8th to 1/16th-inch) slices. Next core the apple and slice it the same way as the sweet potato.
Grease a small casserole pan with olive oil. Carefully stack the sweet potato and apple slices into alternating layers and arrange the layers in a circular or line pattern in your casserole dish. Drizzle with honey, sprinkle spices on top, and dot with butter.
Bake at 350 degrees for 1 hour, or until sweet potato slices are tender.
