Tip for leftovers:
There will be plenty of polenta left. Put the remaining polenta into a rectangular storage container or bread pan and place in the fridge. It will become a firm "loaf" that can be used for other meals by slicing pieces off of the "loaf" and baked on a parchment lined baking tray or fried in a nonstick pan and then topped with marinara sauce or my delicious mushroom gravy.
