Easy Polenta

I made a small batch in the oven in my large Pyrex casserole dish. I was skeptical, but it turned out perfectly with a pretty sparkly top. After cooling it tasted even better as the grit particles were softer. This is a basic recipe with just water, salt and optional butter, but could be used as a base to stir in cheese or other ingredients. I am always looking for an easy way to cook polenta (grits) and this sure beats the slow cooker.
