Add the chickpeas to a food processor bowl fitted with the blade attachment. Pulse until they’re chopped but still have texture, about 6-12 times. Transfer the chickpeas to a mixing bowl. Add the onion, celery, chopped pepperoncini and their juice, dill, capers, lemon zest, lemon juice, and mayonnaise to the bowl and stir to combine. Season with ½ teaspoon salt.
To serve, spoon the salad onto toast, this can also be served in lettuce cups or however you like to eat tuna salad. Makes 3 1/2 cups.
