Chopped salad with tahini and za’atar

Adding tahini to an otherwise familiar tomato and cucumber salad can be a real revelation. You need to start with a brand of tahini which is creamy, nutty and smooth enough to pour. These tend to be the Israeli, Palestinian or Lebanese brands (rather than the Greek and Cypriot ones, which don’t taste as good). This is lovely as a starter, with the blocks of feta, or served alongside some grilled lamb or rice with lentils (with or without the feta).
