Roast on a rimmed baking sheet at 400 degrees for 20-25 minutes or until crisped up and browned, then let cool.Note: You can also double the chickpeas to two cans and adjust seasonings accordingly, if desired. They're excellent and a good filling source of protein for this meatless recipe, but I somehow only had one can in the house today!
Combine all dressing ingredients (I just ran mine quickly through a small food chopper).
Place spinach in a large bowl.
Top the spinach with chopped avocado, tomato, pepper, and roasted chickpeas, then drizzle on dressing and toss to coat.
