Cut the apples and pears into similar sized chunks. Place them, along with the sugar, cinnamon, and water, in a heavy bottomed sauce pan.
Bring to a boil, then reduce the heat to a simmer and cook 15-20 minutes or until the pears and apples are soft. Stir frequently during the cooking time.
About halfway through cooking stir in the raisins.
Divide the granola among 4 bowls and top each with two tablespoons Greek yogurt and ¼ of the pear-apple compote. Drizzle the milk or cream around the edges of the bowl. Serve warm.
