Wash the cauliflower and cut it in a fresh-keeping bag and mix it with salt, garlic powder, cumin powder and olive oil and shake it evenly in a baking tray.
The oven is preheated to 200 degrees. The middle layer is baked for ten minutes until the cauliflower is dry and discolored.
Ten minutes is the amount of cauliflower I put, so the time is short. When baking, you can increase the time according to the amount.
