Heat the oven to 425°F. Prepare a large baking sheet by covering it with a sheet of parchment paper.
Step 2
Add the chopped cauliflower and sliced onion to a large bowl or place right on the baking sheet. Drizzle with oil, and toss to coat the veggies.
Step 3
Add all of the spices, and use your hands to massage all of the spices into the cauliflower and onion, until completely coated. Move over to the baking sheet if not already there.
Step 4
Bake for 20 to 25 minutes, or until golden brown and crispy.
