Meanwhile, in a large wok or skillet heat sesame oil over medium-high heat, add onions, carrots and mushrooms. Saute for about 4 minutes before adding the cabbage, broccoli, colored bell peppers, baby corn, garlic and ginger. Saute until veggies are softened and cooked to your liking tossing them frequently. You can add a splash of water when needed to avoid burning.
