Sweet Potato Cannelloni - cooking recipe

Ingredients

3 sweet potatoes (about 1 pound each)
3/4 cup low fat cottage cheese
3/4 cup fuji apple, diced (skin on)
3 tablespoons chives, fresh, chopped
1 ounce parmesan cheese, grated
1 ounce parmesan cheese, shaved
1/4 teaspoon coarse salt
fresh ground pepper, to taste
oil, for the baking pan
1 tablespoon walnut oil
1 ounce walnuts, toasted, chopped

Preparation

Preheat oven to 375. Wrap 1 sweet potato in parchment, and then in foil. Pierce several times with a fork. Bake until tender, about 1 hour. Let cool. Reduce oven temperature to 350.
Meanwhile, peel remaining sweet potatoes. Using a mandoline or a chef's knife, cut potatoes lengthwise into very thin slices until you have 30 slices. Trim each to a 2-by-4-inch rectangle.
Bring a large pot of water to a boil. Add half the sweet potato slices, and cook until tender, about 2 minutes. Using a slotted spoon, place slices on a baking sheet to cool slightly. Repeat.
Remove peel from baked sweet potato, and puree flesh in a food processor until smooth. Add cottage cheese, and puree until smooth.
Transfer potato-cheese mixture to a large bowl. Stir in apple, chives, grated Parmesan, salt, and pepper.
Coat a 9-by-13-inch baking dish with oil. Place 1 heaping tablespoon filling in center of a sweet potato slice, and roll up. Place, seam side down, in dish. Repeat. (Cannelloni can be refrigerated, covered, overnight; bring to room temperature before baking.)
Brush oil over cannelloni. Bake until heated through, 10 to 15 minutes. Sprinkle with walnuts and shaved Parmesan.
