Soak the chickpeas in water for 2 hours, then drain.
Shred the zucchini and toss with 1 tsp salt. Let sit for 10 minutes, then squeeze out the excess moisture. Set aside.
Combine the soaked chickpeas, garlic, jalapeño, and cashews in a food processor. Pulse until everything is mostly smooth — not a complete paste, but smooth enough to hold together.
Combine the chickpea mixture with the shredded zucchini, and mix together with a spoon, adding about ½ tsp fresh ground pepper.
Form into small patties and bake on a parchment-lined baking sheet at 375F for 25 minutes, flipping after 15 minutes. The patties should be golden on the outside!
To assemble the sandwich, slice and toast the ciabatta, spread one side with fresh avocado, add a few patties along with sliced tomato and fresh arugula. Enjoy!
