I made a lentil soup tonight for something a bit different, and I'm constantly surprised at how good the simple things are. Onion, carrot, celery with olive oil, lentils, stock, bay leaf, and salt and pepper, and the end product was fantastic.
It's better than the pea soup I normally make and about half the effort.
(I didn't take a picture because it's lentil soup, it looks like liquid mush)
I've only ever cooked with the cheap red lentils before, though. Do other varieties have more flavour or is the difference just the colour? Not that the red ones stay red when they cook, either.
