Preheat broiler. Place sweet potatoes in shallow 1-1/2 to 2-quart microwave safe dish. Cover with plastic wrap, venting one corner. Microwave on high for 5 minutes. Coat 10-inch nonstick skillet with vegetable cooking spray. Add sweet potatoes and cook over medium heat, turning occasionally, until golden, about 5 minutes.
Meanwhile, in medium bowl, mix shallot, corn, jalapeno, olives, red pepper, green onions, cilantro or parsley, egg whites, and water. Season with pepper. Pour mixture over sweet potatoes.
Cover and cook over medium heat until eggs are almost set, about 10 minutes. Remove cover. Sprinkle with queso fresco cheese. If not oven-proof, wrap skillet handle in double thickness of aluminum foil. Place skillet 4 to 5 inches from heat source. Watching closely, broil 1 to 3 minutes to finish cooking eggs and melt cheese.
Cut into wedges to serve.
Makes 4 servings.
