Cut the cauliflower into evenly sized florets and place into your food processor, only filling half the bowl at a time.
Blend the cauliflower using the pulse setting. Continue to pulse until it resembles rice. If there are any large pieces, remove them and blend them separately.
Add butter and salt to a medium skillet, heat on medium low setting. Allow the butter to melt before adding the cauliflower.
Sauté the cauliflower for 5-8 minutes, stirring continuously. Serve immediately.
