For the dressing, pour the vinegar into a small jug, season with salt and pepper, then whisk in the oil. Leave to one side.
Perch the peppers over 1 or 2 gas burners (or put them under a hot grill) and blacken them, turning all the time to expose the red skin to the naked heat. When completely charred, tuck them into a plastic bag and leave for 10 minutes. Scrape off the blistered skin, seed and cut the flesh into medium dice. Set aside.
Heat the oil in a large non-stick fryingpan over a medium heat and tip in the onion and shallot. Fry for 3-4 minutes, stirring frequently. Add the garlic, fennel, rosemary and bay leaf. Fry for 5-6 minutes, stirring frequently, without letting the vegetables colour.
Pour 200ml/7fl oz boiling water into a heatproof measuring jug and whisk in the bouillon powder. Pour into the frying pan, tip in the chickpeas and stir. Bubble vigorously for about 5 minutes or until the juices have nearly disappeared. Remove from the heat and cool for a few minutes.
Scrape the contents of the frying pan into a large mixing bowl, then throw in the peppers, lemon zest and parsley. Pour in the dressing and toss gently but thoroughly. Taste and adjust the seasoning. Serve warm or at room temperature.
