Sesame-Ginger Tat Soi
Tat soi is a low-oxalate dark leafy green, and it's quite similar to bok choy. It is delicious when added to raw salads or when lightly sautéed. Look for it at your local farmer's market or natural grocery store. Like other dark leafy greens, tat soi cooks down quite a bit—you'll need a few large bunches to serve a family of four!
