Prepare your dry spice mix: In a small bowl stir together the cumin, coriander, cinnamon, garam masala, black pepper, chili pepper, and salt. Then set aside.
Place the chickpeas back on to the baking sheet (making sure the chickpeas are in a single layer) and roast for 30 minutes at the pre-heated 350 degrees.
Once they have roasted, check for crunchiness. If the chickpeas are still slightly mealy in the middle, turn off the oven and let chickpeas sit in the oven for 10-20 mins (don’t forget to turn off the oven).
