This delicious salad is from drfuhrman.com. I have simplified the instructions so it is a little easier to make. To chop bok choy: Trim the rough edge off the root ends of the bok choy, then cut across the stem just below the leaf. Slice the white stem portion into 3 or 4 lengthwise strips, then cut across to dice. Slice the leafy top crosswise and then cut each strip into 1 inch pieces.
