Grilled Round Steak with Gorgonzola Butter

My sister Sharon makes this, and it is so yummy!

Ingredients:
1 round steak
2/3 c. red wine
2T balsamic vinegar
2T grill seasoning
1/3 c. olive oil
3 cloves fresh garlic, chopped
1/4 c. butter, softened
3-4 oz. Gorgonzola cheese, softened
chopped chives
ground black pepper
  1. Mix together red wine, balsamic vinegar, grill seasoning, olive oil, and garlic in a plastic baggy with the round steak.
  2. Let marinate for a minimum of 2 hours, up to 24 hours. Slosh around the mixture every 30 minutes to an hour.
  3. In a food processor or with a fork, blend the cheese and butter. Add chopped chives and ground black pepper to taste.
  4. Remove the steak from the marinade and broil or grill the steak for 6-8 min. per side for medium to medium-well.
  5. Slice thinly on a diagonal against grain and top with pats of the gorgonzola butter mixture.
