Spiced Sweet Potato Gratin with Goat Cheese

0 Preheat the oven to 400 (200 C) degrees.
1 In a large bowl, whisk together the olive oil, maple syrup, lime juice, garlic, paprika, cumin, oregano, salt and chili.
2 Peel the potatoes if you prefer — I often just scrape off any bruised sections, leaving most of the skin on. Slice the potatoes into ⅛-inch thick rounds, using a mandoline, or use a very sharp knife and great knife skills :)
3 Toss the sweet potatoes in the bowl to coat with the spiced oil. Arrange the potatoes upright in a 2-quart baking dish with the edges face-up, pouring the liquid from the bowl over all. Grind black pepper over the top to taste.
4 Bake 45 minutes. Sprinkle the cheeses evenly over the top and return to the oven for 10 more minutes, until the cheese is softened and melting.
5 Sprinkle the cilantro and pumpkin seeds over the top. Serve warm or at room temperature.
