Drain and rinse garbanzo beans. Place beans in medium sized bowl and mash with potato masher. Add onion, celery, parsley, and stir. If using avocado, add that now and stir in with other veggies.
Blend together sauce ingredients.
Add sauce to the beans and veggies and mix together. Serve on a bed of greens, in tortilla wraps, on a slice of toasted Ezekiel Bread, or mix it with quinoa.
