Place a large Weber Ware Casserole Dish (without lid) on the cooking grill and preheat your barbecue on high for 10 minutes. Once the barbecue has preheated, adjust the burner(s) to medium.
Add the olive oil, butter, and onion to the casserole dish, and cook until the onion is soft, 2 to 3 minutes, stirring as required. Add the raisins, pine nuts, and pistachios and cook until the nuts are toasted, a further 5 to 7 minutes.
