Combine quinoa and water in a medium pot over high heat. Bring to a boil, cover, reduce heat to low and simmer for 15 minutes or until quinoa is cooked.
Meanwhile, combine cabbage, vinegar, salt and pepper in a bowl. Massage the cabbage with your hands for about 5 minutes. Set aside.
Meanwhile, combine all dressing ingredients except for the water in a small jar. Stir well to combine. Add 2 tablespoons of the water. Place the lid on the jar and shake to combine. Remove lid and add the remaining 2 tablespoons of water depending on how thick you want the dressing to be.
When the quinoa is done, divide it onto 3 or 4 plates (or into containers if you are meal prepping) and top with some tofu, slaw, peas and bell pepper. Then top everything with some sliced green onion.
Pour dressing on top right before you are ready to eat and enjoy!
