Heat the oil in a non-stick pan over medium-high heat. (Use a pan just big enough to hold the meat in one layer. The sauce will cook away in a larger pan.) Beef brown on all sides, about 3 to 4 minutes. Put on a plate.
Add the onion and mushrooms to the pan. Fry for 2 minutes. Add the stock, water, tomato paste, mustard and pasta. Mix thoroughly. Bring to a boil, lower the heat to medium, cover with a lid and simmer for 10 minutes. Reduce the heat to low and return the beef to the pan. Let simmer for 2-3 minutes. Taste. You may need to add a little more mustard. There should be a delicate blend of flavors.
Stir in sour cream and add black pepper to taste. Mix thoroughly. Divide between two plates and sprinkle with parsley.
