For a fast, low-calorie dinner, try our take on steak fajitas. Top round steak, a very lean cut of beef, is marinated in soy sauce and lime juice before being seared to perfection in a pan with fragrant garlic. Other lean cuts of beef, like eye of round or top sirloin, will also work in this recipe.


  • ¾ pound top round steak

  • 1 tablespoon soy sauce

  • ¼ cup plus 1 tablespoon fresh lime juice (from 3 limes), plus wedges for serving

  • 1 tablespoon extra-virgin olive oil

  • 1 garlic clove, minced

  • Coarse salt and ground pepper

  • 2 medium green bell peppers, seeded and thinly sliced

  • 1 large white onion, halved and thinly sliced

  • 8 corn tortillas, warmed

  • ½ cup grated white cheddar (2 ounces)

  • 1 large tomato, chopped

  • Cilantro sprigs, for serving


  1. In a shallow dish or bowl, combine steak, soy sauce, and 1/4 cup lime juice. Refrigerate 1 hour, turning steak occasionally. Meanwhile, in a small saucepan, heat 2 teaspoons oil over medium. Add garlic and cook until fragrant, 30 seconds. Remove from heat. Stir in 1 tablespoon lime juice. Set garlic oil aside.

  2. Remove steak from marinade and blot dry with paper towels. Season with salt and pepper. In a cast-iron or heavy skillet, heat 1 teaspoon oil over medium-high. Cook steak until medium-rare, about 2 minutes per side. Transfer to a plate and loosely tent with foil.

  3. Add peppers and onion; season with salt and pepper. Cook, stirring, until vegetables are crisp-tender, 4 to 6 minutes. Stir in reserved garlic oil. Thinly slice steak and serve with vegetables, tortillas, cheese, tomato, and cilantro.
