Mix the brown sugar, sherry, sesame oil, oyster sauce, beef stock, chili garlic sauce, soy sauce, and corn starch to make the stir-fry sauce.
Heat the Evo grill to Medium or Medium High.
Stir-fry the sliced beef with a small amount of peanut oil.
Add the broccoli alongside the beef and stir-fry both separately until the beef becomes browned on the exterior.
Combine the beef with the broccoli and add the stir-fry sauce and the grated ginger. Be sure to mix the stir-fry sauce thoroughly before incorporating with the beef and broccoli. Continue to stir-fry until the sauce becomes a glaze.
Garnish with sesame seeds and sliced green onions if desired.
