In a large bowl, mash the chickpeas until mostly/partially mashed. Then drain the artichoke hearts and finely chop, them into fine pieces, and add to the bowl. Then chop and add the pickles, celery, red onion, and dill, and mix to combine.
You can also make this by adding the chickpeas, artichokes, pickles, celery, capers, red onion, and dill to a food processor and the rest of the ingredients and pulsing for a few seconds until a 'tuna-like' texture forms. But I have found you get the best texture by chopping the ingredients individually.
In a separate small mixing bowl, combine the minced garlic, vegan mayo, white vinegar, salt, pepper, red pepper flakes, if using, lemon juice, nutritional yeast, and nori, if using. Whisk to combine.
Pour the dressing over the chickpea and artichoke mix, then stir to combine and distribute the dressing.
Place in the fridge to chill for at least 30 minutes before serving.
Serve on bread of your choosing along with your desired sandwich toppings.
This Chickpea Tuna will keep in an airtight container in the fridge for 3 to 4 days.
