Place the rinsed chickpeas in a large mixing bowl and mash them with a fork or potato masher until mostly broken down, leaving some chunks for texture.
Add the breadcrumbs, chopped parsley, minced garlic, lemon zest, and a pinch of salt and pepper to the mashed chickpeas. Mix well to combine, feeling the mixture become thicker and more cohesive.
Drizzle in the olive oil and fold it into the mixture, ensuring everything is evenly coated and sticky enough to hold together.
Form the mixture into 4-6 equal-sized patties, squeezing gently to remove excess moisture and shaping them with your hands until they are round and flat.
Refrigerate the patties for 10-15 minutes to help them firm up, making frying easier.
Heat a tablespoon of olive oil in a frying pan over medium heat until shimmering and slightly fragrant.
Place the chilled patties into the hot pan carefully, and cook for about 3-4 minutes per side, until they are golden brown and crispy on the outside.
Gently flip the patties using a spatula, listening for a satisfying sizzle and watching them turn a rich golden hue.
Once cooked through and crisp, transfer the patties to a paper towel-lined plate to drain any excess oil.
Serve the chickpea patties warm, perhaps with a squeeze of lemon or a side salad for a complete meal.
