Coriander and Garlic Marinade

4 cloves garlic, smashed
1 tablespoon ground coriander seeds
1/4 tablespoon black pepper, ground (fresh is best)
2 1/2 tablespoons low-sodium soy sauce
Use a mortar and pestle to grind the garlic, coriander and pepper into a paste (you can use a food processor if that's easier for you). Whisk in the soy sauce until well-combined. Pour into a plastic bag with the filet, and marinate for a minimum of two hours and preferably overnight.
Remove steak, discard marinade, and grill to your liking. Garlicky!
