Preheat large skillet or wok to high heat, then add the oil. Add the salted cod and stir fry to brown it lightly. Next, add the green beans; once beans start to turn a darker shade of green, add the garlic and stir well to combine. Next add half the rice and mix well; then add the remaining rice. Fry the rice mixture for a few minutes, stirring constantly. Next, make a hole in the middle of the rice, add the eggs and scramble them. Add the grapes and edamame. Fold the rice over the eggs to mix them, then season the rice with salt, white pepper, sesame oil, soy sauce and green onions. Plate and serve immediately.
