Got this from the Dynasty website. Use whatever vegetables you like, it's the sauce that makes this dish. Serve it over rice. If I happen to have left over rice I just throw that right in with the veggies/sauce mix. I've used a pkg. of stir fry veggies with the noodles in it and served this over white rice. Yummy! I'm just guessing on the prep time as I use fresh mushrooms. I do not know how long you have to soak dried mushrooms.
