1. Bring 3 cups water to a boil over high heat. Add salt and slowly whisk the cornmeal into the water, whisking occasionally until polenta has thickened, about 20 minutes. Add butter and 1 ounce goat cheese.
2. Heat oil and butter in a large skillet over medium heat. Add onions, mushroom, garlic, salt and pepper, and cook 10 minutes or until browned and caramelized. Add balsamic and honey, scraping to deglaze pan. Cook 2 minutes. Sprinkle with thyme. Spoon polenta into bowls, top with mushrooms and remaining crumbled goat cheese and fresh thyme.
