Prepare a 9 inch glass baking dish with your favorite non-stick spray. Arrange plum slices in the pan. Sprinkle with the wine, and 1 tablespoon brown sugar. Cover tightly and bake in a 425 degree oven for 15 minutes.
In a small bowl, combine granola, cinnamon and 2 tablespoon brown sugar. Sprinkle mixture over plums and return to oven, uncovered, for 10 minutes, or until topping is golden brown and mixture is bubbly.
