This veggie casserole is a twist on the classic cornbread casserole. It features layers of zucchini, corn, and a fluffy cornbread topping. The zucchini adds a fresh and crisp texture, while the corn provides a natural sweetness. The cornbread topping is made with a combination of cornmeal, flour, and buttermilk, creating a moist and flavorful crust. This casserole is perfect for summer gatherings or as a side dish for a barbecue. It's a creative and delicious way to enjoy the flavors of zucchini and corn in one dish.
