Pull the bok choy stalks away from the center one by one and rinse them to remove dirt and debris. Chop 8-10 stalks horizontally into 1/2" thick pieces, all the way from the white bottom to the top of the leaves.
In a large bowl, combine the chopped bok choy, carrots, and 1 Tablespoon of sesame seeds. Mix together. Set aside.
Toast 3 Tablespoons of sesame seeds in a skillet over medium heat, tossing or moving them often to evenly toast them. [This step is optional. You can skip toasting the sesame seeds if you want to keep the salad 100% raw.]
Add the toasted seeds and other dressing ingredients to blender. Mix until it looks like dressing.
Pour the dressing over the bok choy and mix it thoroughly using salad tongs [or what ever it takes to get the job done]. For maximum flavor, cover the bowl and allow the salad to marinate in the refrigerator for 15 minutes or longer.
