Recipe: Chinese green beans

Green beans, snapped into pieces (I had about 4.5 cups- it doesn't really matter...)
1 package mushrooms, sliced
4 clove garlic, chopped
1 tbsp constarch in 1 cup water
1 tbsp soy sauce

Boil the green beans to desired doneness. Cook garlic and mushrooms until mushrooms are tender. Add soy sauce to cornstarch/water, and pour over mushrooms. Cook until thickened (1 min). Add greenbeans to sauce. Toss well and serve.
