Heat butter and oil in a large saute pan until very hot.
Press black pepper into both sides of the steaks.
Place steaks into hot butter and place in a 400° oven. Roast until desired doneness, turning at three-minute intervals.
When done as desired, remove steaks from the oven and place them in separate serving dishes.
Pour off butter and oil. Place cut-up vegetables in the pan.
Pour wine into the pan and saute a few seconds, add brown sauce and bring to a boil.
Place two tomato pieces next to each steak. Pour sauce mixture over steaks proportionately. Serve immediately.
