Mashed Cauliflower with Garlic

I purchased a head of cauliflower on a whim today (I know, I'm so reckless) and made a huge batch of cauliflower rice and mashed cauliflower. We'll be eating the "rice" with lunches this week and I am going to freeze the mashed cauliflower for later. I could probably eat all of this in one sitting if I knew I wouldn't regret it ;)

• 1/2 head cauliflower (or 1 small), stemmed and coarsely chopped
• 2-4 cloves garlic, peeled
• 1T butter or ghee (optional)
• 2T chicken broth or other liquid (optional) 
• salt and pepper to taste

Steam cauliflower and garlic cloves until tender. Transfer to a food processor with butter and broth and mix until desired consistency. Add salt and pepper. Voila!
