Spicy Tuna Steaks

I found this, along with a ton of other tuna recipes here.

Spicy Tuna Steaks

1/4 cup oil
6 cloves garlic, minced or pressed
3 tablespoons coconut aminos or soy sauce
1/4 teaspoon dry mustard
3 tablespoons fresh lemon juice
1/2 teaspoon freshly ground pepper
2 pounds tuna steaks
1 lemon, cut in wedges

In a medium bowl, combine oil, garlic, soy sauce, mustard, lemon juice and pepper. Mix well. Rinse fish under cold running water and pat dry. Place fish in a shallow bowl and cover with marinade. Refrigerate for 1 hour. Cook fish under a preheated broiler for 5 to 7 minutes on each side or until opaque or grill fish on an outdoor barbecue. Serve with lemon wedges. Serves 8.
