This was delicious! My meat-eating husband even liked it. I made the lentil mixture and the potatoes ahead of time so that I could just throw it together into individual portions and heat them up at dinnertime. The only change I made was to use some different spices including cayenne for a little heat. I would definitely try it with sweet potatoes as other reviewers have recommended. You could also use whatever vegetables you have on hand. I think this recipe is very versatile.
