Pat the chicken dry and slash
Peel and slice the onions thinly.
Finely Mince the garlic and juice the lemons. Slice the red pepper and keep aside.
Add the minced garlic and lemon into a bowl. Combine with the mustard, one teaspoon salt and one tablespoon oil. Mix well with a spoon.
Add the onions into the bowl. Mix well with the other ingredients, then place the chicken thighs in the bowl. Combine with the onion marinade, making sure the onions cover the chicken.
Cover the bowl with a cling film and keep it in the fridge overnight.
Remove the chicken from the marinade. Grill in the air-fryer at 190°C for 10 mins to brown. You can also do this in an oven or by frying in a pan. If you’re frying in oil, turn over the chicken after a few minutes to get both sides nicely browned.
Pour the onion marinade into a colander to separate the liquid from the onions.
Heat the remaining oil in a pan under medium heat, then add the onions. Stir occasionally until the onions start to brown. Reduce the heat and stir more often for even browning and prevent sticking. Remove from heat when the onion has turned a golden brown colour.
Add a cup of water to the pan, taste for salt and add more if needed. Then add the liquid that was earlier separated from the onions. Next, add the bay leaves and place the chicken into the pot with the scotch bonnet peppers. Cover the pan and bring the heat back to medium.
Cook for 15 mins, then mix in the olives. Stir with a wooden spoon to prevent sticking and cook for 10 mins before adding the peppers. Stir again and leave to cook for another 5 mins. Remove from heat and serve.
