Whole Foods' "simple Potato Pancakes"

Preheat oven to 400°F.
Spray a baking sheet with nonstick cooking spray. In large bowl, combine potatoes, scallion, onion, egg, flour, salt and pepper, and stir well.
Heat 2 tsp oil over medium heat. Scoop potato mixture, 1/2 cup at a time, into pan and flatten slightly to make a pancake. Add as many pancakes as will fit into pan without crowding and cook 3 minutes per side or until browned. Transfer to prepared baking sheet. Repeat with remaining 2 tsp oil and remaining potato mixture.
Bake pancakes for 5 minutes, or until cooked through and crisp.
