Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). Pat meat dry. Cut the fat edge so that the steaks do not bend when roasted. Heat oil in a pan. Fry the steaks in it over a high heat on each side for approx. 1 minute.
Season with salt and pepper. Put the steaks in an ovenproof dish. Spread tomatoes and chips on top. Sprinkle with cheese. Bake in a hot oven for 6-8 minutes.
Cook rice according to package instructions. Drain the pepperoni, cut into rings and remove the stalk. Mix pepperoni and rice. Serve steaks with pepperoni rice.
