Did you know that, technically, walnuts are seeds, and not nuts? Now you have something to impress the others, something to win at trivia night. But does it matter? Not to the flavor of this delightful sauce, of walnut, mirepoix base, and butter, accompanying the succulent steak with pure nutty goodness. See, if we called walnuts “seeds,” we'd have to call it a seedy sauce, which isn't appetizing. Thank us for your win at trivia night.

Add garlic salt, half the butter (reserve remaining for sauce), and a pinch of salt and pepper. Mash thoroughly until combined. If mixture is too thick, add water, 1 Tbsp. at a time, until desired consistency is reached. Cover and set aside. While vegetables boil, prepare ingredients. -
