Make the dressing: add the rice vinegar, soy sauce, fish sauce, lime juice, peanut oil, sugar, finely chopped chili, and minced garlic to a jar or small bowl. Shake or whisk until the sugar dissolves and the dressing is well combined.
Prepare the slaw: in a large bowl, combine the shredded chicken, green cabbage, red cabbage, grated carrots, bean sprouts, sliced green onions, cilantro, and mint.
Dress the salad just before serving. Pour the dressing over the slaw and toss thoroughly until all the vegetables and chicken are evenly coated.
Transfer to a serving bowl or platter and scatter the fried shallots over the top. Serve immediately for the best crunch.
