Yes, we tried 'Meatza', and it is by far one of our most favourite primal recipes so far. And yes, the crust is made of meat, a combination of ground beef and spicy ground pork. We chose to add a bit of cheese on top as we are okay with eating dairy, but that was not part of the original recipe. You can see the recipe that inspired this creation here.
This was the most filling (and tasty) pizza ever! I thought I'd be giving up pizza by going primal, but instead, we discovered an amazing crust substitute.
