Preparation / Directions:
In a large skillet over high heat, heat 1/2 tablespoon oil. Saute half the beef slices until browned on each side, 1 to 2 minutes per side. It should be rare. Remove to a plate and repeat with remaining beef.
Saute half the mushrooms at a time until golden. Remove to beef.
Add broth, wine, mustard and soup mix to skillet. Cook, stirring, for 2 minutes. Remove from heat and whisk in cornstarch. Return to heat. Bring to a boil, stirring constantly, until thickened.
Whisk in sour cream. Add beef with juices and mushrooms and simmer until beef is cooked through.
Serve over cooked rice or noodles.
