Chicken and Green Beans

I was always wondering what is the "dried green beans" in the menu of Chinese restaurants.
Actual green beans coming out from kitchen is not dry at all, but the external skin is whitened.
One day my friend told me it's fried, not dried.
Today, I tried it and it worked out pretty well. It's really sweet and crunchy.
I deep fried green beans first, and separately fried chicken dusted with a small amount of flour.
I didn't add any spice or sauce, but it's already yummy when I combine two together with a bit of garlic and ginger.
