1 head cauliflower, cut into florets
Olive oil for coating
Salt and pepper to taste
Water as needed (or chicken stock or vegetable stock)
Preheat the oven to 400 degrees and line one or two baking sheets with foil.
In a bowl, toss together the cauliflower, enough olive oil to coat, and salt and pepper to taste. Spread the cauliflower onto an even layer on the baking sheets.
Roast 20 minutes. Using tongs turn the cauliflower on to the other side and roast another 15-20 minutes until browned.
Once the cauliflower has cooled slightly, turn it out into a food processor. Mash until you get a thick puree, adding water as needed. Serve warm.
