Place all sauce ingredients into a small/medium bowl and mix together until blended. Set aside for 30 min to let the flavors mingle. Add extra ingredients to your taste.
While sauce is setting, prepare your veggies. You could cut your kelp noodles into smaller pieces or leave as is (I left mine as is).
Put kelp noodles and other vegetables in a large bowl (saving a few veggies to garnish) and add half of the sauce mixture. Toss the ingredients together until thoroughly coated.
