Preheat grill to MEDIUM-HIGH. Grill steak on one side for 4 minutes then turn and spread a light coating of butter on top of the cooked side.
Sprinkle generously with Parmesan cheese and garlic powder. Continue to grill steak until it reaches desired level of doneness (4 minutes for medium-rare).
Remove steak from grill and allow it to rest for 10 minutes before slicing. Grill the fresh broccoli spears then toss with a little olive oil or butter and the remaining Parmesan cheese.
Thinly slice steak across the grain (diagonally), serve with the grilled broccoli, and enjoy!!
