Zucchini and Onion Saute

This tastes similar to what you'd get at a Japanese Hibachi style restaurant. A friend of mine gave me some zucchini from her garden so we made bread with one and this with the other.

1 onion, cut into slivers
1 medium zucchini (about 3 cups) cut into strips or chunks
butter
soy sauce
garlic salt
sesame seeds

Melt butter in pan. I used about 3 tbls. Add onion and zucchini. Sprinkle with garlic salt and sesame seeds. Drizzle over soy sauce until lightly coated. Saute until onions and zucchini are crisp tender. You could add mushrooms too, but I didn't have any on hand.
