Finely dice or chop up all of the vegetables and toss in a large bowl.
In a blender or food processor, add the dressing ingredients, liquids first: lemon juice, olive oil, rice vinegar, shallot, basil leaves, spinach, nutritional yeast, walnuts, and salt. Blend until smooth.
Add the dressing to the bowl with the diced vegetables and mix well. Enjoy on its own, on tacos, as a side with protein, or scooped up with tortilla chips!
