Grilled Beef Tenderloin with Tuscan Kale and Shallot Confit
Tuscan, or black, kale—known as cavolo nero in Italian—has elongated deep green crinkly leaves. If you can't find it at specialty produce markets, ordinary curly kale is a fine substitute. This marinade is also delicious with pork tenderloin or pork chops. The beef tenderloin is marinated overnight, so plan accordingly.
