Heat the oil in a large saute dish or shallow casserole with a well-fitting lid. Fry the onion, garlic, chicken and chorizo, stirring well. You don't need a lot of oil as plenty of fat will come out of the chorizo.
2 tsp olive oil, 2 cloves garlic, 30 g chorizo, 2 chicken thighs, 1 onion
Add the paprika and peppers when the onion has cooked enough to be translucent, the chicken has started to brown and the chorizo has reduced in size by half. Stir in well to coat the chicken in the spice, and fry for a further minute or so.
1 tsp paprika, 2 roasted red peppers
Add the rest of the ingredients; the rice, canned tomatoes, tomato puree, olives and stock. Add a wedge or two of lemon for extra flavour. Season with salt and pepper.
200 g chopped tomatoes, 2 tsp tomato puree, 1/2 cup rice, 1 cup stock or broth, 30 g olives, 1 lemon
Bring up to a simmer, cover with the lid and turn the heat down to a very gentle simmer. If using a gas hob, you may need a diffuser, even on the smallest ring.
Leave the dish to cook for 18 minutes. Once cooked, turn off the heat and leave to stand for 5 minutes.
Fluff up the rice with a fork, adjust the seasoning to taste, and serve, garnished with fresh slices of lemon.
