This recipe gives the classic grilled cheese a major upgrade with three cheeses, tender tri-tip, zesty chimichurri, and a smoky finish straight from the grill. Each bite through crispy, grilled sourdough promises flavorful smoked beef and deliciously gooey cheese. About the cut: Tri-tip (also known as triangle steak) comes from the triangular bottom tip of the sirloin. It’s a lean and tasty cut that typically weighs between 1 1/2 and 3 pounds. This recipe was created by our partner Lauren Nagel of Bon Appeteach who made the dish on our Bronco Pro Drum Smoker, but you can make it on your grill or smoker.
