In a bowl, combine all the ingredients for the marinade and season to taste.
Pour half of the marinade into another container. Add the steaks, and marinate for 20 minutes at room temperature.
Preheat a grill or skillet over a 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.
