To serve three, use 1 1/2 tablespoons flour, cut the phyllo sheets into quarters, and scale remaining ingredients down by half. Bake the potpies in three (10-ounce) ramekins. (Tuck one quarter of phyllo sheets on top of each ramekin; discard remaining quarter.) Bake 15 minutes or until tops are golden. To reduce prep time, look for prechopped vegetables in the supermarket.
