Rich Lentil Potato Pie

By rights I can’t call this is a ‘shepherd’s pie’ because I just don’t see shepherd’s carrying lentils on their back, and preparing this on their journey into the hills. However, this is a real comforting meal that is lower in fat, and higher in fibre and iron than the regular ‘beef’ variety. You can add whatever vegetables you like, and season to taste. You could also use beans instead of lentils; black beans would be great.
