In a large bowl add the drained & rinsed chickpeas and mash with a fork or potato masher until its in small pieces resembling canned tuna flakes.
Add the shredded carrots, chopped celery, bell pepper, pickles and sunflower seeds to the bowl and give it a stir to combine. Then add the mayo, mustard, lemon juice, salt and pepper and stir everything to combine.
Last add the fresh chopped basil and dill and stir one more time. To make the sandwich, toast the sliced bread, then layer it on the bottom with some fresh greens and 4 or more fresh basil leaves, add a spoonfull of the chickpeas salad, a little more basil if you want, a tomato slice, salt & pepper & the top slice of bread. This is also great on just a bed of greens, in a wrap, or as a dip for crackers. Enjoy!
To store, keep covered in the fridge for about 4 days.
