Place the steak or steaks in the freezer for about 10 minutes. Remove the steak from the freezer and slice it against the grain as thin as you can manage. The slices should be the size of the egg noodles.
Place a large pot of water over high heat and bring to a boil. Once boiling, add some salt and the egg noodles, and cook according to package directions. Drain thoroughly and reserve noodles in the cooking pot. Add 2 tablespoons of butter and half of the dill and chives to the pot, and stir to combine.
