The Sauce: The piquant base comes from the prototypical Thai flavor trinity: soy sauce, fish sauce, and garlicky chile paste. Lime juice cut with sugar adds zing.
The Extras: Toss the soft noodles with chunks of flavorful lime-marinated chicken breast. Then top with thinly sliced lemongrass, raw shallots, and torn basil leaves. Result: ultra- fresh and lively.
