Sweet Potato and Feta Pancakes

1. Place grated sweet potato, cilantro, cayenne, egg, flour, and feta in a bowl and blend with a fork. Season to taste with salt and pepper.
2. Heat oil in a large skillet over high heat until very hot (if you drop a dollop of batter, it should immediately start sizzling).
3. Add batter by the spoonfuls. Mold them into a pancake shape with the back of a spoon. Cook until both sides are browned, about 2 minutes per side.
4. Sprinkle pumpkin seeds if using and top with sour cream, yogurt, or applesauce.
