Using 1 tortilla for each serving, place 1/4 cup of each cheese over half the tortilla's surface, top with 3 slices of sweet potatoes and season with salt and white pepper to taste.
Fold the tortilla over the filling to make a semicircle. Before serving brush the top lightly with oil and sprinkle with ancho chile powder. Bake for 6 minutes or until crisp. Serve 2 per person and drizzle each with the maple glaze
