Japanese Steak House Vegetables

We like the vegetables at the Teppanaki Japanese Steak houses where they cook in front of you. Here is our home approximation:

zucchini, peeled and cut into little short pieces (the size of tootsie rolls or a little bigger)
oil
1/2 an onion, sliced
mushrooms, if you have them
fresh bean sprouts
Kikkoman reduced sodium soy sauce
Mrs. Dash
sesame seeds
real butter

Heat the oil and saute the onion until transparent. Add the zucchini and stir fry until almost done. Add a few shakes of Mrs. Dash, add the mushrooms, saute for a few minutes, add a couple tablespoons of real butter; when it melts stir in the bean sprouts, cook until just softened, season with a few dashes of soy sauce and sesame seeds. Serve with rice and a protein.
