Heat 1 tbsp sesame oil in a large wok or skillet over high heat and cook beef in batches 4 minutes until browned; set aside.
Add remaining oil and garlic, then broccoli; stir-fry 5 minutes until tender-crisp.
Return beef to pan, add soy sauce, and toss for 2 minutes.
Serve beef and broccoli over warm brown rice.
