Instructions: Cut each kidney in half lengthways and snip out the core with scissors.

Slice the kidneys thinly.

Heat the oil in a non-stick frying-pan, add the kidney and cook over a high heat until browned.

Transfer the kidneys to a plate and set aside. Add the onion to the frying-pan and cook over a medium heat for 5-10 minutes or until golden and translucent.

Add the mustard powder, paprika, Cayenne and ginger and cook for 2 minutes, then add the tomato puree, Worcestershire sauce, sherry and water, season with pepper and simmer for 5 minutes.

Return the kidneys to the pan and cook for a further 5 minutes. Serve with plenty of brown rice and steamed broccoli.
