Heat oven to 200C/fan 180C/gas 6. Heat
the oil in a large roasting tin on the hob.
Brown the lamb steaks in the tin over a high
heat, about 1 min each side.
Add the onion to the roasting tin with the
oregano. Pour over the wine and throw in
the tomatoes. Scatter the olives over the top,
then place the tin in the oven for 15 mins
until the lamb is cooked. Scatter with flat-leaf
parsley and serve with boiled new potatoes.
