I discovered this burger recipe in a fitness magazine last summer and I am in love.  They are low cal (128 calories), high in protein (about 28 grams), very low in fat (1 gram) and they make a great snack or meal.  Be sure to use the extra lean ground turkey.  I also discovered last summer that regular lean ground turkey has NINE grams of fat in a 4 oz. serving whereas extra lean ground turkey has only ONE gram of fat.  It's a huge difference and I did not find a flavor sacrifice.
