In a medium saucepan, brown 1# stew meat, cubed roast or ground beef. Add 2 cups water, 1 3/4 milk and 1 tablespoon margarine. Heat slowly over low temperature until margarine melts. While stirring, slowly add entire amount of soup mix. Reduce heat and simmer, uncovered, for approx. 30 minutes. Optional: add one can (13 oz.) drained mushrooms and 1/4 cup sour cream. More water or broth may be added for desired consistency. Not recommended for crockpot; stove-top only.
