In a small bowl, whisk together the soy sauce, cornstarch, and water until smooth. Set aside. Heat the sesame oil in a large wok or skillet over medium-high heat. Add the garlic and sauté for 30 seconds until fragrant. Add the broccoli, carrots, mushrooms, and bell pepper. Stir-fry for 4–5 minutes until the vegetables begin to soften. Add the snow peas and cook for another 2 minutes, keeping the vegetables crisp-tender. Sprinkle in The Holly Tree Organic White Pepper Powder, The Holly Tree Organic Ginger Powder, and Salt. Toss well to coat the vegetables evenly. Pour in the prepared soy sauce mixture and stir continuously for 1–2 minutes, until the sauce lightly coats the vegetables. Transfer to a serving plate and garnish with The Holly Tree Organic Natural Sesame Seeds.
