Preheat oven to 400°F.
Put cauliflower rice in a microwave-safe bowl and cook for 2 minutes on high, stir, then cook for another 2 minutes. Let cool 1-2 minutes.
Spoon cauliflower onto a piece of cheesecloth or a fine mesh strainer (a clean dish towel will do in a pinch), and squeeze out as much liquid as possible. (The drier the better).
In a large bowl, mix together cauliflower and remaining ingredients.
Line a baking sheet with parchment paper and spray with cooking spray.
Using a tablespoon, scoop cauliflower mixture and squeeze into cylindrical shape in palm of hand. Place on baking sheet and spritz with cooking spray.
Bake 15 minutes until bottoms are brown and flip. Bake an additional 15 minutes or until brown and crispy.
