How to Make It
Light a grill or heat a grill pan. In a bowl, combine the tomatoes with the scallions, cilantro, mint, jalapeño, garlic and lemon juice. Season the salsa with salt and pepper.
Rub the steak with the oil and season with salt and pepper. Grill over high heat until nicely charred outside and medium-rare, 3 minutes per side. Transfer the steak to a carving board; let rest for 5 minutes. Thinly slice the steak across the grain and serve with the salsa.
