What is this?

Anyone seen this before? It is actually cauliflower. I found it at the Santa Monica farmer's market and it is my new favorite food. It has a mellow, slightly peppery flavor. It is best roasted, simply with a little olive oil and a dash or two of salt. It also pairs well with broccoli or rabe. If you happen to see it at your local market or store, grab it and bring it home. You will be happy you did!
