To make the polenta - add the milk, water and salt to a medium saucepan. Set the pan over medium-high heat and bring to a low simmer. Slowly pour in the polenta, whisking constantly the entire time. Turn the heat down to low and partially cover with a lid. Cook for about 25 to 30 minutes, whisking every few minutes to get out any lumps (be sure to scrape the sides and bottom of the pan). You want the polenta to thicken and have a creamy consistency. If it starts getting too thick, you can add in a little more milk (a tablespoon or so at a time).Remove from the heat and add in the brown sugar and vanilla extract. Whisk to combine.Ladle the polenta into bowls. Top with some diced strawberries, a splash of half and half and some chopped nuts. Serve immediately.
