Fresh green beans are available year round, but their real season in the northern hemisphere is the summer to early fall. I count crispy green beans among one of my favorite vegetables, so I enthusiastically eat as much as possible.
There are several kinds of green beans - large and fat, flat and broad, and so on. These are skinny little haricots verts or French beans. They can be rather expensive, so I like to cook them as minimally as possible. Here they are paired with julienned fresh ginger and carrot, stir fried then steam-cooked in a frying pan. The ginger adds some heat and the carrots add sweetness. They are cooked in less than 5 minutes, though allow some extra time to cut the ginger and carrot. You can use fatter green beans if you can't get haricot verts - allow for a couple more minutes of cooking time.
This is great hot or cold, so it's a very good bento vegetable dish. It will hold in the refrigerator for 2 to 3 days, so if you buy a big bag of green beans at the market it's worthwhile to make a batch of this.
