1. If you do not have soba sauce, just add 2 tablespoons of low-sodium soy sauce. Keep adding more soy sauce, one tablespoon at a time until you reach the desired level of saltiness. You should be able to find soba sauce in any Japanese market.[br][br]2. I didn't pickle the cabbage and red peppers because I wanted other flavors in the soba bowl. Feel free to pickle them with the other vegetables if you like.
