Tikka masala spice does not belong only on chicken. Cauliflower and chickpeas, roasted at 400 degrees F (200 degrees C) with a homemade spice blend of garlic powder, cumin, coriander, paprika, turmeric, cayenne, and salt, drizzled with olive oil, turn into something that could replace any meat dish at the table. Thirty minutes in the oven. No paste, no cream, no sauce. The spice blend is generous by design.
