Asparagus is known for containing a  high level of antioxidants that slows down the process of aging. Its crunchy and refreshing taste makes it an optimal ingredient for appetizers. Simply peel and blanch the asparagus, add fresh walnuts and dress with a light vinegrette. For a healthier diet, Chef Wang recommends using less oil and eating lots of fresh vegetables.
