To make the vinaigrette, combine all of the ingredients in a blender or small food processor until smooth.
Remove the outer leaves & core of the cabbage. Slice into thin ribbons or smaller bite sized pieces.
Slice & cut the bell peppers into small pieces. Thinly slice & cut the onion into small pieces. Roughly chop the cilantro.
Combine all fresh ingredients with crumbled cheese & pistachios in a large bowl. Pour the dressing over the top about 1/4 cup at a time. You can always add more later!
