Remove green leaves and stem from cauliflower. Roughly chop into small to medium sized chunks.

Put cauliflower chunks/florets into blender and fill with water until the pieces are just barely floating. Depending on the size of your blender this may need to be done in batches. Pulse a few times or blend on a low setting very briefly until pieces are riced. This will happen very quickly!

Pour out into a strainer set over a sink or large receptacle. Wait for a minute or two for the water to drain, and press down with a spatula to remove extra moisture.

Dump raw cauliflower rice into a bowl, add oil and salt and mix together until evenly coated. Cover bowl with lid or plastic wrap and microwave on high for 3 minutes.

Remove from microwave, fluff, and it's ready to serve. Eat with curry, lentils, or whatever else you eat rice with. Or use as rice substitute in dishes.
