What do you call a recipe like this? "Chickpea of the sea" is a little too cute, but "garbanzo bean salad" could be anything, and "mock tuna salad" sounds like one of those recipes that starts with a box of crackers and a can of cream-of-something soup.
Still, there's no more accurate way to describe it than "tuna salad, with chickpeas instead of tuna." Or maybe "lumpy hummus with pickle relish and celery." Whatever you call it, it's damned tasty. Also pretty healthy, gluten-free, and vegetarian- and vegan-friendly (just use tahini or another mayonaise alternative.)
Whether or not you're actively avoiding tuna, you should definitely try this version the next time you're making lunch.
