Cut steaks into 2-3 pieces each. Then using your fist, a small saucepan, a meat mallet, rolling pin or potato ricer bash each piece of meat until it’s about 1/2cm (1/4in) thick. Rub steak with oil and sprinkle with a big pinch of fine salt.
Heat a large frying pan, griddle pan or your BBQ. When it’s super hot add steaks and cook for 1 minute on each side or until well browned. Divide steaks between two warm plates to rest while you make the sauce.
Keeping pan off the heat, add vinegar and stir to scrape up any tasty bits from the bottom of the pan. Add cream and pepper and return to the heat. Simmer for a few minutes until sauce has thickened a little. Pour sauce over steaks and finish with salad / veg on the side.
