Preheat the oven to 180C
Cut the preserved lemon in half and remove the seeds. Dice up really fine and set aside.
Dice up half of the olives and slice the others to garnish the dish. Set these aside also.
Add a glug of olive oil to the pan and fry off the dice onion until softened. Stir in the minced garlic.
Now add in the diced preserved lemon, the spices, salt and tomato paste. Stir well on a low heat.
If using jarred chickpeas add them in with their juice. If using tinned chickpeas drain them and add in with 200 ml of water.
Now add the diced olives and stir to combine all of the ingredients.
Pop the lid on and put into the oven for 1 hour.
You’ll need to check in on the dish every 15-20 minutes to make sure its not drying out. If the chickpeas are looking a little dry add in water bit by bit to keep it moist and slightly saucy.
After the hour has passed and you’ve checked that the chickpeas are soft and flavoursome take the dish out and serve up garnished with some lemon slices, chopped parsley and the sliced olives.
