After moving to a new state with two toddlers in tow, I came up with effortless fajitas. They make an easy weeknight meal on the grill or in a cast-iron skillet. —Shannen Mahoney, Odessa, Missouri

  • 1 beef top sirloin steak (3/4 inch thick and 1 pound)
  • 2 tablespoons fajita seasoning mix
  • 1 large sweet onion, cut crosswise into 1/2-inch slices
  • 1 medium sweet red pepper, halved
  • 1 medium green pepper, halved
  • 1 tablespoon olive oil
  • 4 whole wheat tortillas (8 inches), warmed
  • Optional: Sliced avocado, minced fresh cilantro and lime wedges


  1. Rub steak with seasoning mix. Brush onion and peppers with oil.
  2. Grill steak and vegetables, covered, on a greased rack over medium direct heat 4-6 minutes on each side or until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; and medium-well, 145°) and vegetables are tender. Remove from grill. Let steak stand, covered, 5 minutes before slicing.
  3. Cut vegetables and steak into strips; serve in tortillas. If desired, top with avocado and cilantro, and serve with lime wedges.
