I used to make a vegetable soup with brown lentils but to be honest, the colour started putting me off it. That and I ate it made it too often. There's nothing like eating something too much to inspire boredom. I've had a good break and I decided it was time to start eating them again. I found this yummy red lentil curry. It's fairly similar to the old soup but it provides a lovely change in both colour and flavours. I add some chicken stock (and less tomato paste), yogurt to aid its creaminess, and a little lemon juice as any good Indian chef would.
Any other lentil suggestions would be heartily welcomed.
