This recipe is a favourite that I adapted from Joyous Health. In the picture, I made it with organic bison, from a local butcher. However you can make it with ground turkey or even lean ground beef. I recommend that you buy organic and grass fed beef if you have the option, and a good local butcher should have that.
To make it as healthy as possible, you can wrap it in a massive piece of iceberg lettuce, and I added in some tomato, avocado, onion and sprouts for extra flavour.
