Place the grated carrots, raisins, chickpeas, and parsley, if using, into a mixing bowl.
In a small bowl or Pyrex measuring cup, whisk together the tahini, garlic, lemon juice, vinegar, curry powder, maple syrup, salt, and water.
Pour the tahini sauce over the carrots, raisins, and chickpeas. Mix well, so that all of the ingredients are well-coated. Taste the chickpeas; add any additional salt, lemon juice, or vinegar as desired.
Serve the chickpea salad in pita pockets with a handful of your favorite salad greens, with crackers, or in a bowl. Alternatively, store in an airtight container in the fridge for up to 4 days.
