For the steak and marinade: Whisk solid ingredients into melted butter. Place steak into a Ziploc bag and pour marinade mixture over steak. Keep the butter for more marinating. Place the Ziploc bag into a shallow pan of lukewarm water to marinate. When steak is finished marinating, grill steak on both sides until desired doneness is achieved.
For the veggies: Grill asparagus until tender. Top with parmesan cheese and drizzle with balsamic vinegar.
One steak per person; veggies serve multiple people depending on how much asparagus and potatoes are used.
