In a bowl, combine all the ingredients for the marinade and season to taste.
Sea salt and freshly ground black pepper, 1 cup extra virgin olive oil, 3 garlic cloves, 2 shallots, 3 tbsp. fresh basil, 2 tbsp. fresh parsley, 2 tbsp. fresh rosemary, 2 tbsp. fresh thyme, 2 tsp. dried oregano, 3 tbsp. red wine vinegar, Sea salt and freshly ground black pepper
Pour half of the marinade into another container. Add the steaks, and marinate for 20 minutes at room temperature.
2, 15- oz. beef sirloin steaks
Preheat a grill or skillet over high heat.
Cook the steaks for 5 to 7 minutes per side for a medium-rare steak (or adjust to your preferred doneness level).
Spread the remaining marinade (the half that you didn’t use for the steaks) over a cutting board, and press both sides of each steak onto the marinade-covered board to pick up the herbs.
Slice the steaks and serve well coated with the marinade.
