Mix together the Hoisin sauce, rice vinegar, chili garlic sauce, and water, and set aside.
Place the tempeh in a small sauce pan, with enough water to just about cover. Steam the tempeh for about 3 minutes. Drain.
Heat the olive and sesame oils in a sauté pan, over medium high heat.
Add the broccoli, snow peas, onion, bok choy and carrots to the pan and saute for about 8-10 minutes until vegetables are tender.
Crumble the steamed tempeh into the vegetable mixture.
Add the sauce mixture to the pan, and reduce the heat to low.
Add the rice, and stir to combine everything and heat through for about 3-5 minutes. Add more water if the sauce seems too thick.
Taste, and season with tamari or soy sauce if desired.
