Few foods say "summer" in the same way as a T-bone steak grilled to perfection and served with sides such as a baked potato and salad. This steak, a staple of barbecue season, provides a source of protein and a number of nutrients. The exact nutritional value of your T-bone steak depends, in part, on how it's cut and prepared.
