It all depends on your health and fitness goals and your dietary needs and restrictions. Generally, a good meal plan emphasises vegetables, fruits, and whole grains, including lean meats, poultry, fish, beans, eggs, and nuts. It limits saturated and trans fats, sodium, and added sugars and must have controlled portion sizes. But as mentioned, every meal plan is unique. As long as you get your macronutrients through your meals, then your meal plan is good and balanced.
