Step 1

Place the garlic, oregano, basil, parsley, rosemary, and salt into a mortar or small bowl, and mash into a coarse paste. Stir in the olive oil, balsamic vinegar, and white pepper until evenly blended. Scrape half of the mixture into a separate small bowl; set aside. Spread the remaining half of the herb mixture evenly over the steaks. Set aside to marinate for 1 hour.

Step 2

Preheat an outdoor grill for medium-high heat, and lightly oil the grate.

Step 3

Cook the steaks on the preheated grill for 7 minutes, then turn over, and coat with the reserved herb mixture. Continue cooking 7 minutes more for medium-well, or until your desired degree of doneness has been reached.
