Steam the potatoes and beans in a steamer basket set over a pan of boiling water for 8 mins. Arrange the salmon fillets on top and steam for a further 6-8 mins, or until the salmon flakes easily when tested with a fork.

Meanwhile, mix the dressing ingredients together along with the clementine juice. If eating straightaway, divide the salad leaves between two plates and top with the warm potatoes and beans and the clementine slices. Arrange the salmon fillets on top, scatter over the herbs and spoon over the dressing. If taking to work, prepare the potatoes, beans and salmon the night before, then pack into a rigid airtight container with the salad leaves kept separate. Put the salad elements together and dress just before eating to prevent the leaves from wilting.
