Place the almond flour, psyllium husk powder, coconut flour, flax meal, baking powder and salt in a small bowl and stir with a spoon to combine.
Add olive oil and water. Mix with a spoon to combine.
Roll / shape into two balls and top with optional sesame seeds if desired.
Either grease or add a small square of parchment paper to two microwave safe bowls just bigger than the roll. Mine was 4 inches wide x 2 inches deep.
Microwave one at a time, on high for about 2 - 2.5 minutes depending on how firm you like your roll. Mine took 2.5 mins at 850 - 900W.
Slice in half and fill with your favorite filling. (Option to toast before filling).
Storage: Best fresh but can be covered for 2 days.
