For a vegan option, substitute the goat cheese with a plant-based alternative or a drizzle of high-quality olive oil. The jammy tomato topping can be made ahead of time and stored in the refrigerator for up to 3 days. Reheat gently before serving. Experiment with different herbs in the tomato mixture, such as rosemary or oregano, to customize the flavor profile. Ensure the baking sheet is hot before adding the polenta rounds to achieve maximum crispiness.
