Cut cauliflower heads into 1 inch cubes, and place in the bowl of a large food processor
Process until finely ground, about 1 minute. Texture should resemble corn grits
Over medium-high heat, place oil, onion, salt & pepper into a medium saucepan
Saute until onion begins to brown
Add garlic, chicken stock, and processed cauliflower to pan and stir
Cover and cook for 10 minutes. Remove lid, and cook for another 10-15 minutes, or until most of the liquid has been absorbed
Remove from heat, and serve warm!
