Make the dressing:
In a small mixing bowl, combine the Sweet & Sour Sauce, fish sauce, and lime juice; set aside.
In a small bowl, toss apple slices with lemon juice to prevent browning; set aside. With a paring knife, peel the orange down to the flesh. Working over a large bowl, cut along the dividing membranes of the fruit, cutting towards the center and letting the segments fall in the bowl. Discard the membrane and the peel. Add the apple, shallot, chiles, grapes, arugula, and chicken. Toss gently. Add the dressing, gently tossing again to mix thoroughly. Transfer to a shallow bowl or platter, sprinkle with the peanuts and mint leaves, and serve.
