Place the tofu in a large bowl and mash it with a fork until there are no big pieces.
Add celery, red onion, and parsley to the bowl.
To a separate smaller bowl, add all the sauce ingredients, and stir until smooth. You might have to mash the avocado cubes with a fork to get it creamy.
Pour the sauce over the tofu mixture and stir until everything is combined. Add salt and pepper to taste if needed.
Enjoy on your favorite whole-food plant-based bread, with crackers, or stuffed inside pitted avocado halves.
