Heat the oil in a large skillet or wok on medium-high heat. Add the carrots and onion and stir-fry for 2 minutes.
Add all of the remaining vegetables and garlic and stir-fry for another 5-7 minutes until the vegetables are tender-crisp.
Make a soy sauce mix by adding soy sauce, brown sugar, sesame oil, chicken broth, and cornstarch.
Pour the sauce over the veggies and cook until the sauce has thickened (about 5 minutes). Sprinkle with toasted sesame seeds and serve over cooked rice.
