Also, seems that Greek Yogurt is the new miracle food and a perfect post workout snack. High protein, low cal, and nutrient rich.
Here's a link to a Toronto Star article written back in October.
"Greek Yogurt has about 18 grams of protein per serving, at least double that of regular yogurt. Its thickness also makes it a good substitute for sour cream or as a marinade. Or just eaten with honey and nuts."
Just remember, your workout doesn't stop with the sweat. 80% of your results are dependent on your nutritional habits, especially right after your workout.
