I love pizza, well I loved Pizza. I have traveled all over Western Canada and parts of the US, and I always sought out the best Pizza in every town and City I was in. Unfortunately that is somewhat over as I am no longer looking for the right crust or sauce, and all I focus on is the toppings; Meat and Cheese, with some spices for added flavor.
You can pick any toppings you like, any meat and cheese though in this realm stick to aged versions, or no carb options like pizza mozzarella. As for meats you can find many without nitrates, and even if you do come across them, you shouldn't be eating enough quantities to worry about issues, just focus on the carb content of these as sometimes they include hidden sugars.
I will grate up some cheeses and combine them to act as a binder/crust, and layer meat and cheese on some parchment paper (A must!), while sprinkling some spices between layers. Afterwards I bake it at 375 degrees for 7 minutes, remove from the pan onto a cutting board and slice it with my Pizza wheel!
If you want to make an actual crust, you can combine a few eggs and 1 lbs ground chicken meat with some aged cheddar cheese, spread it out between parchment, pack it down thin and then bake at 350 for 20 minutes. Remove from heat, let cool add toppings and replace in oven for another 7 minutes, depending on final cheese topping you might want to go longer for a more golden crust.
Enjoy!
