Tenderize steak. Remove excess fat. Chop hamburgers and add curry powder to dressing mixture. Spread mixture on steak and roll as a jelly roll. Tie with string. Put oil into pan and heat. Add steak roll to pan and roll to brown on all surfaces. Reduce heat. Add water and simmer. Cover and cook, rotating meat, for approximately 30 minutes. Liquid in pan is excellent for gravy stock.
