Heat a wok or large skillet over high heat and add the oil. Add the onions and stir-fry until just wilted, about 30 seconds. Add the snow peas and stir-fry until nearly crisp-tender, about 2 minutes more. Add the sauce and stir-fry to coat, about 1 minute.
Transfer to a platter or large bowl, sprinkle with the nuts and serve.
