Start by preparing and cutting all the vegetables and measuring your ingredients so that they are ready to go. Once you begin stir-frying, it goes very quickly.
In a wok or large skillet, heat canola oil over high heat until almost smoking. Add the peppers and onion while stirring constantly. While continuing to stir, add successively the squash, broccoli, eggplant, tofu, garlic, and teriyaki sauce. Cook, stirring, constantly for 2 minutes. Add the bok choy, sprouts, pepper, and salt and cook, stirring, until crisp-tender, about 2 minutes more.
Stir in snow peas and sesame oil and remove from heat. Serve immediately.
