In a small bowl, stir together cashew butter, chilli garlic sauce, soy sauce, and water to make a smooth paste. If you wish, toast cashews lightly in a small frying pan or oven for a few minutes. In preheated wok or frying pan, cook onion in oil over high heat for 3 mins or until beginning to brown. Add carrot and cook for 1 min., add broccoli and cook for another 30 seconds then add red pepper, bok choy and snow peas, cooking just long enough to heat through. Add sauce, stir to combine.
Sprinkle with cashews and serve over rice.
