Taken from Ji Pin Su Shi (Best Vegetable Dishes), a 30-cent, 5-in-square, paperback cookbook from Wal-Mart in China. Simple, home-style Chinese fare. Chinese cooks are expected to determine the proportions of condiments and seasonings. Everything is "ge shi liang"--to taste. I've suggested amounts, but if they don't seem right, just trust your own tastebuds. China has several varieties of green beans, and they go by different names in different parts of China. I think 'jiang dou' may refer to the yard-long beans, but any variety should taste good in this recipe. The amount of garlic listed strikes me as over the top. Try it if you dare. I'll be using less.
