Heat some cooking oil in a large pan over a medium to high heat. Add the diced onion and pepper and cook for about five minutes until it softens.
Add the chicken into the pan and turn the heat up to a high heat. Cook for a few minutes, stirring occasionally until there are no more visible pink bits.
Sprinkle in the paprika and season with salt & pepper. Cook for a minute.
Pour in the chicken stock, then add the rice, butternut squash and harissa paste.
Stir it well, then turn the heat down to a medium. Cover it with a lid or tin foil then leave it to simmer for about 20 minutes, or until the liquid has been soaked up and the butternut squash is tender.
Take the lid off then stir through the peas and chopped parsley. Serve and enjoy.
