Found this recipe at about.com. Papaya contains a strong enzyme called papain which dissolves oil and dead skin cells; it is one of the best non-abrasive masks that you can use. The strawberries also helps exfoliate those dead skin cells.
I want to try this soon; sounds like a great on-the-go breakfast or healthy snack. I might replace half of the oil with unsweetened applesauce. From Australian Women's Weekly magazine. (yield is an estimate)
