Mix the granola with the honey by drizzling the honey evenly over the granola as you stir. On a serving plate, make 3-inch circles of granola in even thickness, dividing the granola/honey mixture evenly among the servings. Top each of the granola circles with a watermelon slice and place a slice of kiwi on each watermelon circle. Spoon the yogurt over the kiwi and watermelon as though it were hollandaise sauce on eggs benedict. Top each watermelon benedict with a grape half; skin side up as a garnish reminiscent of the olive slice on eggs benedict.
