What is a good substitute for salad oil?

When counting calories, use yogurt, pureed roasted vegetables or cottage cheese as the base for a dressing in place of salad oil. If it's a matter of health rather than weight, choose one of the healthier oils available, such as grapeseed, olive or sesame oil.

The purpose of oil in a salad dressing is simply to help distribute the flavoring and bind them to ingredients in the salad, so anything that is light on taste but has a rich, semi-thick consistency will do. Make a truly low-calorie oil substitute for your salad by combining 2 tablespoons each of corn starch and chicken broth to 1 cup of water and heat until it's the desired consistency.
