In a bowl add the coconut flour, ground flaxseed, psyllium husk powder, baking powder, onion powder, garlic powder, salt and mix thoroughly.
Add the oil and stir until combined.
Pour the beaten eggs into the mixture and stir until combined.
Add the boiling water and mix into a dough.
Let the dough sit for at least 10 minutes to firm up.
Pre-heat the oven to 200C/400F degrees.
Split the dough into 6 balls.
Roll out one ball in between two sheets of parchment paper.
Cut the dough in a circle (I use a small saucepan lid).
Spoon your mixture of choice into half of the dough.
Using the bottom parchment paper roll over half of the dough over the filled section and press down on the edges to seal it.
Repeat until the dough is used.
Place all calzones on a baking tray lined with parchment paper.
Brush the calzones with the beaten egg for a glaze.
Bake for 20-25 minutes until golden and firm.
