Sauté onions and garlic in a bit of oil until they are soft and golden.
Add mushrooms, zucchini, and chorizo and increase the heat.
Stir constantly in the pot until the vegetables are delicious and roasted, then add paprika, oregano, thyme, cumin, and bay leaves.
Stir well for about a minute, then add chopped tomatoes, vegetable stock, tomato paste, and cream.
Place the chicken fillets well into the stew so they are covered and let it simmer under a lid for 20-30 minutes, until the chicken meat is tender.
The chicken can then be taken out of the pot and shredded with two forks or cut into cubes.
Put the chicken back into the pot and season with salt and pepper.
