Instructions

1. Divide the polenta between two 9-inch round nonstick baking pans, and refrigerate until set, about 1 hour.
2. Steam the potatoes in a double boiler or steamer basket over medium heat until tender. Set aside and let cool.
3. Place the onions in a medium saucepan and sauté over medium heat for 15 minutes, or until well browned. Add water 1 to 2 tablespoons at a time to keep the onions from sticking to the pan. Remove from the heat and set aside.
4. Preheat the oven to 425° F.
5. Divide the pesto in half and spread over each of the two pans of polenta. Arrange the potatoes over the pesto, top with the caramelized onions, and sprinkle with the nutritional yeast, if desired. Season with salt and pepper. Bake for 10 to 12 minutes. Let sit for 10 minutes before serving.
