Mix all the dry ingredients in a mixing bowl.
Melt the butter and mix it with olive oil. Add the eggs and beat the mixture with a whisk.
Combine the wet and dry ingredients and work the dough with your hands. In case your flaxseed flour or psyllium powder has a stronger power and the dough appears dry, add some sparkling mineral water.
Place the dough in the freezer for 10 minutes.
Cut small balls out of the dough and roll them between two parchment papers so that you get 5mm (0,12 inches) thin pita bread. Grill the flat pita bread on a dry pan from both sides for 2-3 minutes.
If you would like your Pita bread to be crunchy, grill them for 4 minutes from both sides.
