Add all of the ranch dressing ingredients to a medium bowl and mix together.
Now add the chickpeas and use a potato masher or fork to mash to preferred texture. I like about ½ the chickpeas mashed and leave the other ½ whole. Add in the celery, red onion and cilantro, and stir to combine. Layer onto bread with lettuce. Enjoy!
Notes
The chickpea filling stores well in an air-tight container in the fridge for up to 2 - 3 days.
