Preheat oven to 350º F. In a small saucepan, add plums and water. Cook over medium heat 5 minutes, or until plums are softened. Transfer to a food processor or blender, and process until mixture is a thick paste.
In a large bowl, combine plum mixture, apple juice, olive oil, oats, raisins, almonds, walnuts, sunflower seeds, and coconut. Stir well, making sure everything is well coated. Spread out on a baking sheet, and bake 5 minutes.
Stir granola, and bake another 5 minutes, or until lightly browned. Let cool (will become more crispy as it cools), and store in an airtight container.
