Polenta slices with tomato sauce and fresh vegetables

You may know polenta mainly as a creamy, hot side dish served with italian food, but polenta is much more versatile than that. It gets quite firm when it cools down, so you can easily cut it in shapes and use it as a gluten-free base for hearty slices, veggie burgers and the like. This recipe uses this quality of polenta to make hearty, pizza-like slices that you can eather serve hot or cold. They are perfect for taking to uni or work with you, and you can use whatever vegetable you have at hand for the topping.
