Heat the olive oil in a large paella pan and then add the chopped onions, pimientos, garlic, chillies and rosemary.
Sauté the vegetables for a few minutes until the onions begin to soften, season the chicken and the rabbit with salt and pepper and add to the pan along with the chorizo
Fry, stirring frequently, over a high heat to lightly seal the meat.
Add the rice and mix well with all the other ingredients to ensure that each grain of rice is coated in oil.
Pour in the sherry and allow it to evaporate before adding around a litre of boiling water.
Reduce the heat, bring the liquid to a simmer and sprinkle on the saffron
, stirring well to combine it with everything well.
Add the tomatoes and season well, simmering for about 15 minutes and stirring well to prevent the rice from sticking, but not too much.
Add the snails, topping up with more boiling water if necessary, and stir through so that they are submerged.
Cook for a few minutes over a medium heat and then stir in the peas
and season to taste.
Take the pan off the heat, cover with foil and leave the rice to stand for 5 minutes.
Garnish, sprinkle with a handful of chopped parsley
and arrange the lemon wedges around the pan.
