Ingredients

Tex-Mex Chili Rub:

1 tablespoon paprika

2 teaspoons light brown sugar

1 1/2 teaspoons chili powder

1 teaspoon ground cumin

1/2 teaspoon chipotle chile powder

1/2 teaspoon garlic powder

Kosher salt

1 1/2 pounds skirt steak

1 tablespoon olive oil

1 lime, juiced

Peppers and Onions:

2 red bell peppers, cut into 1-inch strips

2 yellow bell peppers, cut into 1-inch strips

2 large red onions, thickly sliced

3 tablespoons olive oil

2 limes, juiced

Kosher salt

Neutral oil, for oiling the grill grates

Warm tortillas, for serving

Suggested toppings: guacamole, sliced pickled jalapenos, lime wedges, mango salsa, chopped scallions, shredded Cheddar

Directions

  1. For the Tex-Mex chili rub: Mix together the paprika, brown sugar, chili powder, cumin, chipotle chile powder, garlic powder and 1 teaspoon salt in a small bowl. Toss the skirt steak in a container with the olive oil and lime juice, then rub with the spice mixture. Refrigerate, covered, for at least 30 minutes and up to 2 hours before cooking.
  2. For the peppers and onions: Heat a cast-iron pan over medium-high heat until hot. Toss the peppers and onions in a bowl with the olive oil, lime juice and 1 teaspoon salt. Add the pepper-onion mixture to the hot pan and cook, stirring occasionally, until the vegetables are tender and the edges are charred, 8 to 10 minutes. Set aside.
  3. Prepare a grill for medium-high heat and brush the grill grates with oil.
  4. Grill the skirt steak until marked, 4 to 5 minutes per side for the thicker pieces for medium rare, or 2 to 3 minutes per side for the thinner pieces for medium rare. Transfer to a cutting board and thinly slice.
  5. Serve with the warm tortillas and toppings.
