I am planning dinner for four. Beef Stroganoff is the main. I have read so many recipes; I am boggled. Please share your favorite tried and true. I read tomato. No tomato. Mushrooms, no mushrooms. Red wine, no wine. I am confused. The last one I read is in Oct. Real Simple. No mushrooms, no wine. Beef, onion, seasonings and yogurt instead of sour cream. (And I love my sour cream . . .) and RS has medium tomato, chopped.
