  • 6 Boneless Skinless Chicken Thighs
  • 6 small Tortilla Wraps, warmed
  • 3 Peppers/Capsicums, sliced
  • 1 large Red Onion, sliced


To Serve


  • Create your marinade and reserve 1 tbsp. Mix the rest with your chicken in a large bowl (or zip lock bag) and leave to marinate at room temp for 30mins. You can marinate longer, just pop it in the fridge and take out 30mins before you intend on using it.
  • On a 30cm x 45cm (12” x 18”) tray, combine your onions and peppers with the 1 tbsp of marinade. Create 6 spaces for your chicken then place them on too.
  • Turn your grill/broiler on to high heat and place your tray about 6” underneath. Cook for 10mins or until the chicken begins to char, then take out, flip the chicken and veg and place back underneath for another 8mins, or until the chicken begins to char on the other side. Timings will vary so just be vigilant. If the chicken chars too quickly place the tray lower or turn down the heat.
  • Place chicken on a chopping board to rest for at least 5 mins to soak back up the juices. Slice into strips, making sure you cut at an angle and against the grain. Stack your fajitas and enjoy!



a) Fajita Seasoning - Be sure to check out my homemade fajita seasoning!
b) Cooking timings - will vary, so just be vigilant. If the chicken chars too quickly then simply turn down the heat or lower the rack. Also, the chicken will carry on cooking as it rests, so you want it only just cooked after broiling.
c) Calories - Based per fajita, assuming all the marinade is used (i.e pouring the pan juices over) and without any toppings.
