Chickpeas and Swiss chard with yoghurt

This is comfort food at its best, served with some steamed rice. Don’t worry if you don’t have coriander at home already: it’s a nice little garnish but the dish holds its own perfectly without. Make this up to 6 hours ahead if you like, up to the point before the lemon juice and yoghurt are added. Assemble before serving and serve at room temperature or just warmed through.
