Clean, dry the chicken fillets, and then lightly pound the thicker parts to get them to an even thickness.
Blend all the other ingredients and then pour this sauce over the steaks. Mix until every piece is coated well. Refrigerate overnight.
Remove the chicken from the fridge at least half an hour before you begin cooking so that it comes close to room temperature. When ready to cook, shake the excess marinade off the chicken and grill on a bbq/charcoal grill (or under the broiler grill of your oven) for about 6-10 minutes per side or until cooked through and they begin to char.
While the steaks are cooking, pour the marinade/sauce into a small saucepan, add about half a cup of water and simmer until the sauce thickens and is cooked. You can use this delicious sauce to brush the cooked steaks when they come out of the oven or to serve on the side.
Serve your delicious Peri Peri Steaks with fries, fresh salad and a cold drink. Enjoy!
