Make the Sauce: Make the sauce by whisking all the sauce ingredients together in a bowl. Set aside.
Cook: Heat the vegetable oil in a large wok or skillet then add the onion and carrot and cook for 1 minute over medium-high heat. Stir in the garlic and cook for 30 seconds or until aromatic. Add the prepared beef and spread it out as much as possible. Let it sear, without touching them for 2 minutes and then toss. Cook for another minute, tossing as necessary.
Finish & Serve: Stir in the sauce and mix until combined. Add the green onions and toss. Drizzle with sesame oil and remove from heat. Garnish with sesame seeds and serve over cooked rice.
