Sweet Potato with Roasted Pepper-Balsamic Stuffing
Preheat broiler. Scrub sweet potato; prick several times with a fork. Cut in half lengthwise. Place halves, cut sides down, in a shallow microwave-safe baking dish. Add the water; cover with vented plastic wrap. Microwave on 100% power (high) for 8 to 10 minutes or until tender, rearranging once. Cool slightly.
Scoop pulp out of potato halves, leaving 1/4-inch shells. Place pulp in a medium bowl and mash with a potato masher or beat with an electric mixer on low speed. Add cream cheese, roasted pepper, vinegar, soy sauce, garlic powder, and black pepper. Stir or beat until smooth, adding a little milk if necessary to reach desired consistency.
Spoon mashed potato mixture into potato shells, pressing gently. Place stuffed potato halves on a baking sheet. Broil 4 to 5 inches from the heat for 3 to 4 minutes or until heated through and lightly browned. Sprinkle with chives. If desired, serve with sour cream.
