Place 1 cup of the chickpeas in a large bowl and mash with a potato masher or fork until chunky puree. Squeeze the lemon on top.
Add the un-mashed (about ½ cup) chickpeas, celery and shallots to the mashed chickpeas. You can also mash all the chickpeas if you like.
In a small bowl, combine yogurt/mayonnaise, mustard, herbamare and pepper.
Pour on top of the chickpeas and salad ingredients and combine to coat well with dressing. Adjust seasonings to taste.
Store leftover in the refrigerator for up to 3 days.
