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.
In a separate smaller bowl, make the sauce by adding all the sauce ingredients and stir until smooth. You might have to mash with a fork to get the avocado creamy.
Pour the sauce over the tofu mixture and stir until everything is combined.
Add salt and pepper to taste if needed.
