In a small bowl, mash 2 tablespoons raspberries; strain, reserving juice. Place greens on salad plates. Top with the orange sections, star fruit, kiwi and remaining raspberries.
In another bowl, whisk the oil, sugar, vinegar, salt, onion powder and reserved raspberry juice. Drizzle over salads. Serve immediately.
Editor's Note: One medium pomegranate may be substituted for the raspberries. Remove the pomegranate seeds; mash 2 tablespoons of seeds, reserving juice. Use the juice in the salad dressing, and serve the remaining pomegranate seeds in the salad.
