Use leftover chicken breasts from our Simple Chicken Noodle Soup when making this light dish.
In a large pot, bring 1 inch salted water to a boil; add bok choy. Cover, and cook until tender, 3 to 5 minutes; drain, and let cool.
In a bowl, whisk together lime juice, fish sauce, sugar, and cayenne. Add chicken, snow peas, and shallots; toss to combine. Top chicken mixture with mint, and serve alongside bok choy.
