I love lentils and cook with them frequently. I copied the recipe that forms the base of this one from a book many years ago. I can't remember the book any more, and the truth is that the recipe has gone through many iterations over the intervening years. I have added North African flavours and pared the recipe down so that you can now (if you are quick) go from preparation to eating this warming vegetarian soup in as little as 30 minutes!
This warming dish, served with crusty bread makes an ideal winter lunchtime treat. To make it even more North African in flavour why not try adding some spice (ras el hanout or harira would be my choices)?
