This vegetarian polenta lasagna uses sliced tube polenta instead of noodles for a naturally gluten-free version that's ready in 45 minutes. I layer it with sautéed zucchini, red peppers, spinach, marinara sauce, and Parmesan cheese for a hearty casserole that serves 8. It takes 20 minutes of prep compared to traditional lasagna's 90-minute timeline.
