- In a large saucepan, heat your oil over a a moderate flame and gently fry off your onions, pepper and garlic in that order, otherwise aliens will steal your spoon.
- Add in your mushrooms, lentils and beans, season with all seasoning things and stir.
- Pour in your tomatoes and top up with water, add in any ingredients you haven't yet and bring to the boil. Let it simmer for at least 30 minutes, ideally longer. I accidentally left mine on low and slow for about 3 hours, and it's definitely not done the flavour any harm, even if the lentils have lost their original bright colouring.
- Serve atop gloriously simple, blanched and seasoned greens. Blanch with some garlic in the water if you need any extra titillation. Why would you? Are hearty, lentil based dishes not titillating enough at this chilly time of year?!
