This vegetable and rice casserole is a versatile and satisfying dish that can be customized with your favorite vegetables. A medley of colorful vegetables, such as bell peppers, carrots, peas, and corn, are sautéed until tender and then mixed with cooked rice. A creamy sauce made with vegetable broth, milk, and a blend of herbs and spices is poured over the vegetable and rice mixture. The casserole is then baked until the flavors have melded together and the top is golden and bubbly. This dish is a great way to use up leftover vegetables and can be served as a main course or as a side dish for a complete and nutritious meal.
