Melt butter in large saucepan over medium-high heat. Add garlic and sauté until softened, about 1 minute; do not brown. Add water, broth, salt and pepper. Bring to a boil. Gradually whisk in the cornmeal, being certain to break up any lumps that might form. Reduce heat to medium-low and continue to cook, stirring often, until thick and creamy, adding more water if too thick, about 15 minutes (this part is more like 5 minutes and it will get this really fast so be quick). Remove from heat; stir in parsley and Parmesan cheese. Taste for seasoning. Serve immediately, topped with sauce from the entree, if desired.
**Note: In place of the parsley I use dried Italian style herbs and put in while I'm heating the broth. I don't usually have parsley on hand or I would use it! ;-)
