Start by opening a can of chickpeas and draining the liquid. Rinse them under cold water, then transfer to a large mixing bowl. Using a fork, mash the chickpeas gently, leaving some whole for texture.

Add your desired amount of buffalo sauce, followed by a generous dollop of vegan mayonnaise. Dice some celery and, if using, finely chop the red onion, then add these to the bowl. Combine all the ingredients thoroughly.

After mixing, taste the Buffalo Chickpea Salad and adjust seasoning with more buffalo sauce, salt, and pepper as needed.

Take two slices of bread and spoon a generous portion of the chickpea salad onto one slice. Layer some fresh lettuce on top.

Place the second slice of bread on top to complete your sandwich. If packing for later, keep salad and bread separate.
