Southwest Flank Steak with Fresh Tomatillo Salsa

For tomatillo salsa, combine the tomatillos, cilantro, jalapeño, garlic, and 1/8 teaspoon salt in a food processor. Cover and process until mixture is chopped. Set aside.

Trim fat from steak. Score both sides of the steak in a diamond pattern; set aside. Stir together chili powder, cumin, garlic powder, ground pepper, and the remaining 1/8 teaspoon salt (see Tip) in a small bowl. Sprinkle evenly over both sides of the steak.

For a charcoal grill, place the steak on the grill rack directly over medium coals. Grill, uncovered, for 17 to 21 minutes for medium (160 degrees F), turning once halfway through grilling. (For a gas grill, preheat the grill. Reduce heat to medium. Place the steak on the grill rack over the heat. Cover and grill as directed.)

Transfer the steak to a cutting board. Cover loosely with foil; let stand for 5 minutes. Thinly slice the steak diagonally across the grain. Serve with the reserved tomatillo salsa. If desired, sprinkle with queso fresco (or Monterey Jack).
