Core a crisp apple (such as Granny Smith or Fuji) and put the wedges in a microwave-safe bowl. Sprinkle with a teaspoon of brown sugar and a pinch of cinnamon and nutmeg, then toss to cover. Cover the bowl with a microwave-safe plate and cook for 3 to 4 minutes on high. Add raisins or a dollop of nut butter after the apples cook. The apple is less than 90 calories and provides 3 grams of filling fiber; raisins also add more iron, vitamin C, and fiber.
