In my Mexican steak fajitas recipe, tender strips of sirloin pick up plenty of spicy flavor from a marinade seasoned with cayenne pepper and cumin. This colorful dish is speedy and satisfying. —Shirley Hilger, Lincoln, Nebraska


  • 1/4 cup orange juice
  • 1/4 cup white vinegar
  • 4 garlic cloves, minced
  • 1 teaspoon seasoned salt
  • 1 teaspoon dried oregano
  • 1 teaspoon ground cumin
  • 1/4 teaspoon cayenne pepper
  • 1 pound beef top sirloin steak, cut into 1/4-inch strips
  • 1 medium onion, thinly sliced
  • 1 medium green pepper, thinly sliced
  • 1 medium sweet red pepper, thinly sliced
  • 2 tablespoons canola oil, divided
  • 6 flour tortillas (10 inches)
  • Optional: Shredded cheddar cheese, picante sauce and sour cream


  1. In a large bowl, combine the orange juice, vinegar, garlic and seasonings; add the beef. Turn to coat; set aside. In a skillet, saute onion and peppers in 1 tablespoon oil until crisp-tender; remove and set aside.
  2. Drain and discard marinade from beef. In the same skillet, cook beef in remaining 1 tablespoon oil until it reaches desired doneness, 2-4 minutes. Return vegetables to pan; heat through. Spoon meat and vegetables onto tortillas. If desired, top with cheese and serve with picante sauce and sour cream.
