Rinse the dried 135 grams dried chick peas well and soak them in plenty of water overnight.
The next day, drain and rinse the chickpeas.
In a pressure cooker over medium-high heat, add 1 tablespoon olive oil, the ½ carrot, ½ large onion, and ½ rib celery in a single layer and fry them undisturbed until browned on one side. Flip and brown the other side.
Add drained chickpeas and then slowly add enough water to cover the chickpeas by 1-inch. Add the 1 teaspoon salt and then seal the lid, setting the pressure to high.
Turn up the heat to high and let the cooker come up to full pressure (it should make a loud whistling noise). Set the timer for 15 minutes and then lower the heat so that you're getting a low steady whistle. If the whistling stops, just turn up the heat a bit.
When the timer is up, turn off the heat and let the pressure drop naturally.
When the pressure has dropped open the lid and discard the vegetables. Ideally you'll want to let the chickpeas cool in the liquid and soak overnight, but if you're in a hurry, you can cool the chickpeas quickly by putting the pot in a large bowl full of ice water for about 15 minutes.
To make the dressing whisk together the 2 tablespoons olive oil, 1 tablespoon red wine vinegar, 1 teaspoon fresh thyme, ½ sprig fresh rosemary, 2 grams garlic, ½ teaspoon lemon zest and ¼ teaspoon salt.
Roughly chop the chickpeas and add them to a bowl with the 1 roasted red bell pepper, 45 grams preserved lemons, 45 grams kalamata olives, 30 grams red onion, 30 grams celery, 13 grams flat leaf parsley, 1 tablespoon sumac and dressing.
Mix everything together and serve as a sandwich or salad.
