1 Cook noodles in a large Dutch oven as per instructions. I put a bit of salt and oil in my cooking water. Cook, drain, and return to pot.
2. In a large, heavy frying pan, melt butter, add mushrooms and saute until lightly browned. Add white wine here if desired. When mushrooms are done, scoop them out and add to the cooked noodles - leave any juice behind.
3. Add the Wondra flour to the mushroom juices and mix - then add some gravy. As the gravy in the pan starts to boil and thicken, add the rest of the gravy - lengthen with water and more Wondra if necessary.
4. Chop beef into mouthsize pieces. Add beef and the gravy to the noodles and mushrooms. Mix all together and serve.
