I took my favorite family recipe (that was not grain free, and involved a frozen pastry pie crust), and tweaked it, to make a primal and paleo version. It took a few trial runs before I found a comparable version of the original. It also has a very low carb count, only 3.1 net carb per slice! Can also be made without the crust, and then it is only 2.2 net carbs per slice.
