1 jarred roasted red pepper, chopped
3/4 C jarred marinated artichoke hearts, drained and chopped
1/2lb fresh mozarella cheese, thinly sliced

In a bowl, combine the reserved spinach and the goat cheese. Spread half the cheese mixture over the polenta in the baking dish. Scatter the mushrooms and red pepper on top. Cover with the remaining polenta rounds. Top with the remaining cheese mixture, the artichokes, mozzarella and tomatoes. bake until the mozzarella melts, about 15 minutes. Let set for 15 minutes before serving.
