Prepare the base by finely dicing the cabbage, cucumbers, and chives; place in a large mixing bowl.
To make the dressing, add spinach, basil, garlic, shallot, lemon juice, olive oil, walnuts, nutritional yeast, salt, and rice vinegar to a high-speed blender.
Process the dressing ingredients until completely smooth and vibrant green.
Pour the dressing over the diced vegetables in the mixing bowl.
Fold the dressing into the vegetables until thoroughly and evenly coated.
Serve as a salad or as a dip with tortilla chips.
