- 2 tablespoons olive oil
 - 3 cloves garlic, minced
 - 1 teaspoon chopped fresh parsley
 - 1 teaspoon chopped fresh thyme
 - 1/3 cup dry red wine
 - 1/2 teaspoon dry mustard powder
 - salt and pepper to taste
 - 4 (8 ounce) flat iron steaks

- Whisk together 2 tablespoons of olive oil, 3 cloves minced garlic, parsley, thyme, red wine, 1/2 teaspoon mustard powder, salt, and pepper until combined. Pour into a resealable plastic bag over the flat iron steaks. Squeeze out excess air, seal, and marinate for 1 hour at room temperature, or 4 hours in the refrigerator.
