  • 1 pound beef flank steak
  • 1 pound chicken breasts boneless and skinless
  • 1 cup salsa I prefer mild but you can also use medium, plus extra for serving
  • 2 tablespoons lime juice
  • 2 tablespoons fresh cilantro chopped
  • 2 cloves garlic minced
  • 1 tablespoon chili powder
  • 1 teaspoon cumin
  • ½ teaspoon salt
  • 8 ounces frozen bell peppers and onions one of the stores I shop at calls it “fajita mix”
  • 16 flour tortillas warmed
  • 1 avocado sliced, optional
  • 1 cup shredded cheddar cheese optional
  • 1 cup sour cream optional


  • Slice flank steak lengthwise in half then crosswise into strips—about 2-inches long. Slice chicken in similar way—first lengthwise then into strips about 2-inches long by ½-inch wide. Place meat into slowcooker.
  • Add 1 cup salsa, lime juice, cilantro, garlic, chili powder, cumin and salt.
  • Stir well to combine. Cover and cook on LOW 5-6 hours.
  • About ½ hour before serving, add frozen onion and bell pepper mixture until warmed through.
  • Serve meat and vegetable mixture in warmed flour tortillas. Top with optional avocado, cheese, sour cream and/or extra salsa, if desired.
