Heat the oven to 220C/425F/Gas 7.
Heat the olive oil in a non-stick frying pan and sauté the onion for a few minutes, to soften.
Add the chicken pieces and fry until browned. Stir in the chorizo and paprika and heat for a few minutes. Pour in the double cream and stir.
Transfer to the oven and cook for 10-12 minutes, until the chicken is cooked through.
Meanwhile, mix the cooked rice, cooked peas and vegetable oil in a bowl.
To serve, spoon the cooked rice onto a serving plate and serve the chicken and chorizo dish alongside.
