Potato (or Sweet Potato) Latkes (Kopie)

*****
Ingredients
•3 lbs potatoes (or sweet potatoes)
•1 medium onion
•1/3 cup unbleached white flour
•1/2 tsp baking powder
•1 cup Egg Beaters or similar egg substitute
•2 Tbsp chopped fresh parsley
•kosher salt (to taste)
•freshly ground black pepper (to taste)
•nonfat, zero-calorie olive oil flavored cooking spray

Instructions
Place three non-stick baking sheet pans in the oven and preheat to 450 degrees Fahrenheit. Peel potatoes and remove dry outside layer of onion. Grate together (either on a box grater or in a food processor with a shredding disk). Squeeze handfuls of grated mixture to reduce liquid content as much as possible, then add to large mixing bowl. Stir together with flour, baking powder, egg substitute, parsley, and salt and pepper to taste, and set aside. Working with oven mitts, carefully pull warmed baking sheets from oven and spray with nonfat, zero-calorie olive oil flavored cooking spray. Spoon mixture onto baking sheets, creating small pancakes 2 to 3 inches in diameter, leaving at least 1 inch gap between. Bake 5 to 8 minutes per side, or until golden brown, before spraying tops with cooking spray and flipping with a spatula. Serve hot, with fat-free sour cream and/or unsweetened applesauce.
