With the emphasis on calorie reduction, weight loss, and healthy cooking, this set was specifically designed for those who are serious about good health and good cooking. Each cover has a steam ventilation knob allowing you to cook just below the boiling point--preventing healthy vitamins and minerals from being cooked out. The two steamers allow you to steam vegetables or fish. Both skillets are coated on the inside with non-stick coating, reducing the need for oils or grease. All pieces of this cookware set have a polished finish on the outside and easy grip handles. If you want to make changes in your diet or you just want to maintain healthy eating patterns, this is the set for you!
