In a small bowl, whisk together the low-sodium soy sauce, oyster sauce, brown sugar, cornstarch, and sesame oil until smooth. Set this mixture aside; it will be the delicious glaze for your stir fry.
In your wok or large skillet, heat the olive oil over medium-high heat. Once hot, add the minced garlic and ginger, sautéing for about 30 seconds until fragrant. Be careful not to let them burn!
Add the sliced onion and bell pepper to the pan, stir-frying for about 2-3 minutes. Next, toss in the carrots and mushrooms, cooking for an additional 2 minutes. The vegetables should be vibrant and slightly tender but still crisp.
Stir in the broccoli florets and snap peas, followed by the kosher salt. Continue to stir-fry for another 3-4 minutes until the broccoli turns bright green and tender-crisp.
Pour the prepared sauce over the sautéed vegetables, tossing everything together for about 1-2 minutes until the sauce thickens and coats the vegetables. The cornstarch will create a glossy finish to your stir fry.
Spoon the cooked white rice into bowls and top with the vegetable stir fry. Garnish with sesame seeds and chopped green onions if desired. Enjoy your nutritious, colorful meal!
