Fill the kettle and put it on.

Peel and chop the potato into 1.5 inch chunks.

Roughly chop one of the onions and both peppers and put them all to a medium saucepan.

Peel and crush 3 garlic cloves with the side of the knife and add them to the saucepan.

Add the lentils and three teaspoon of minced ginger.

Add the turmeric and tamarind to the saucepan also. 
  
 
 Step 2:

Cover the mixture in the pot with boiling water and simmer over a medium flame.

You'll simmer the vegetables until the lentils are very soft, about 20 to 30 minutes.

If the vegetables start to stick or dry up, add more boiling water and turn the heat down.

Whilst this mixture is simmering, chop the remaining onions and fry them in a large saucepan over a medium heat in 2 tablespoons of oil.
