Cut the peppers into 2x2cm pieces and chop finely the onion & garlic.
Heat the oil in a wide saucepan and gently fry the chopped vegetables.
Drain the chickpeas.
When the onion is transparent and soft, add the paprika and the chickpeas. Cook for two minutes, then add the stock.
Bring it to boil, then place the fish slices on top of the stew. Season with salt & pepper and simmer for 8-10 minutes (under cover).
Chop the parsley and chilli.
When the fish cooked through, scatter with the parsley, chilli and lemon zest. Squeeze the lemon juice into the sauce.
Serve with crusty bread.
