Place the shredded cabbage and scallions in a large bowl. Heat a medium dry skillet over medium-low heat. Add nuts and let toast, stirring every 20 seconds or so, until the nuts are lightly browning. Add to cabbage mixture.
In a small bowl, whisk together the ingredients for the dressing. Pour over the cabbage and toss until everything is well combined and cabbage is coated. Taste and add more salt if desired. Let sit for 5 minutes before serving.
