A baked potato with beans and cheese is an inexpensive, meat-free meal that contains several essential nutrients. The calorie count for an average serving of this meal is under 400.
According to the USDA National Nutrient Database, a medium-size baked potato weighing 173 grams contains 161 calories. An ounce of mozzarella cheese, made with part-skim milk, contains 72 calories, and a half-cup of baked beans contains 133 calories, bringing the total calorie count to 366.
Obviously, changing the portion size of each food in the meal will affect its caloric value. A large baked potato, for example, contains 278 calories in 299 grams of cooked weight. A small potato, at 138 grams cooked weight, has 128 calories.
Beans are a good lean protein source, according to MedlinePlus. Cheese is also a good source of protein, although it contains a relatively high level of fat per serving. Baked potatoes are low-fat and contain vitamins and fiber in the skin.
