Preheat the oven to 350° F. Combine the first ten ingredients in a large bowl and mix well. Put the mixture into an ungreased loaf pan. Spread steak sauce over the top of the loaf and sprinkle with chopped rosemary. Bake uncovered for 1 to 1-¼ hours, or until no pink remains in the center. (If using a meat thermometer, the internal temperature should be 160°F.) Pour off any liquid. Garnish with rosemary, if desired.
