Step 1

In a medium-sized bowl combine the coconut flour and the almond flour and salt. Note if making the nut-free option use sunflower seed flour in place of the almond flour and set aside.

Step 2

Melt the unsalted butter and set aside.

Step 3

To the dry ingredients add the melted butter and combine quickly.

Step 4

Next, add the two whole eggs and combine.

Step 5

Melt the mozzarella cheese in the microwave using 30-second intervals, mixing in between until fully melted but not crispy. This should take about 3 rounds in the microwave depending on the power of your microwave.

Step 6

Once it comes out of the microwave mix well until fully incorporated. You can also melt the mozzarella cheese in a double boiler.

Step 7

Add the melted mozzarella cheese to the mixture and knead the dough with your hands until all the cheese is blended well into the pie dough. I recommend you do so between two sheets of parchment paper so that the dough doesn't stick to your hands. Alternatively, you can use a stand-up mixer with the dough hook.

Step 8

Once the dough forms divide the dough in half to make the top and bottom of the pie crust.

Step 9

Place the pastry dough in the refrigerator to rest the dough and allow the dough to chill. This will make it easier to work with and will produce the flakiest crust.

Step 10

Roll out the dough between two sheets of parchment paper for both the top and bottom of the crust and place back into the refrigerator for another 15 minutes to cool again and make it easier to work with the dough

Step 11

Pre-heat oven to 350 degrees Transfer one rolled crust into a 9-inch pie pan. Being careful to smooth any cracks.

Step 12

Fill the pie with strawberry rhubarb filling and dot the pie with sliced butter.

Step 13

Add the top crust and make 5-6 slits to the top of the pie to let the steam vent as it cooks.

Step 14

Bake the pie until the topping is lightly brown around 35-40 minutes.

Step 15

In a large bowl combine the sliced rhubarb, strawberries, sugar substitute, and vanilla extract.

Step 16

Next, sprinkle the salt and psyllium husk powder and combine well.
