Another great Ottolenghi salad. As with many salads it is very often the dressing that makes it. It is especially true of this salad and so you can feel very comfortable swapping out some elements and adding in others. For example in the version I made here I swapped out some of the tomatoes for a diced yellow pepper. A greater ratio of peppers to tomatoes has the advantage of reducing the tendency for the salad becoming too watery in the fridge, if you make ahead of time or have any left overs.
