This recipe is always a winner and can be modified to suit what vegetables you have handy.
Use organic where possible.
Stir-fry leeks, onions, garlic and spices in oil until slightly onions are slightly opaque, in a large saucepan (or I prefere slow cooker)
Add all other ingredients ensuring there is enough fluid to cover all vegetables (you may need to add some water).
Bring to the boil then allow to simmer for twenty minutes or until the sweet potato is soft.
Serve in a bowl with lots of fresh coriander on top. Can be also served with a small portion of rice.
This recipe makes a delicious breakfast when reheated and even tastes nice cold for lunch. Can be frozen, so I usually double the ingredients and make a big batch in my slow cooker.
