Turkey.

I love turkey, not just at Christmas but all year round!

The white meat of a turkey is almost all protein! Perfect if you are trying to slim down or make gains! 

It's a good source of  iron, zinc, potassium and phosphorus, vitamin B6 and niacin.
Turkey also contains  tryptophan, which is used to help your body produce serotonin, the happy hormone and  Melatonin, the sleep hormone but not in a high enough quantity to drastically improve your mood or lull you to sweet slumber so ignore that little myth!

Just be aware that delicious skin is where all the fat is, at least with a bird that size you can make loads of meals if not you could just settle for turkey sandwichs!
