I eat a salad nearly every day for lunch and so am always trying to come up with different varieties. This one has been a favourite for a couple of weeks now. The lentils and feta provide a good source of protein and the feta and dressing some healthy fats - meaning that this salad keeps you full for the rest of the afternoon. It can be made in advance and taken into work as a packed lunch. This can be made with any type of lentil - but I particularly love the nutty flavour and firm texture of the dark speckled lentils.
