Heat oven to 450°F. Spray 15x10x1-inch rimmed sheet pan with cooking spray (or line the sheet pan with aluminum foil and spray the foil for easy clean up).
Combine the soy sauce, brown sugar, garlic, ginger, and oil in a zip top bag. Mix well. Add the beef, onions, and broccoli to the bag and toss to coat evenly. Let it marinate for at least 30 minutes.
Spread the mixture on your sheet pan and roast 15-20 minutes or until it reaches an internal temperature of the meat reaches 160 degrees.
While the beef and broccoli is cooking, make some white rice to go with it.
Once the meat has reached the correct temperature, serve it on top of the rice. Sprinkle some of the green onions or sesame seeds on top
