1/3 cup balsamic vinegar
1/3 cup soy sauce
1/4 cup vegetable oil
2 tbsp Worcestershire sauce
1 tbsp honey
1 tsp Italian seasoning; dried
1 tsp garlic powder
1 tsp dried mustard

1. Whisk together balsamic vinegar, soy sauce, oil, Worcestershire sauce, honey, Italian seasoning, garlic powder, and dried mustard.

2. Add your steaks and the marinade to a zip lock bag, tossing the steaks a few times to coat. Press the excess air out, seal the bag, and chill for 15 to 20 minutes.

3. Use tongs to transfer steaks to a preheated grill. Cook until desired doneness is reached. Allow to rest for 5 minutes before serving.

Notes:
Makes enough marinade for 4 to 6, 8 ounce steaks.

Don't marinate too long, 15 to 30 minutes is plenty of time.
