  • 1 ½ lbs chicken breast fillets (700 g)
  • 2 peppers
  • 3 tablespoon fajita seasoning


  • Add chicken breast fillets to a slow cooker. Sprinkle the fajita seasoning on top, and cover with a lid.
  • Cook the chicken on high for 2-3 hours, or on low for 4-5 hours. The chicken breasts should be completely cooked through, and there should be no pink meat.
  • Then, use two forks or meat shredding claws to shred the chicken. Slice the peppers and add them to the slow cooker. Cook for another hour until the peppers have softened.
  • Remove the slow cooker fajita chicken and serve immediately, or keep them on the warm setting for a few hours until you’re ready to serve dinner.
