Lentils offer a valuable amount of iron, along with plenty of folate and low-fat protein. They're also a very good source of niacin and potassium.
I too added sweet potato, which I'm sure gave it extra nourishment and flavour. I gave it a whizz with the stick mixer (it's incredibly thick), so served it with a dob of light Greek yoghurt and a dash of ground cumin. Very filling and satisfying. A little more garlic wouldn't go amiss! - 06 Jan 2012 (Review from Allrecipes AU | NZ)
Something else. I also added 750g of sweet potato to this recipe and it gave it a whole new level. - 05 Aug 2009 (Review from Allrecipes AU | NZ)
