Print Recipe


  • ½ Cup Coconut flour
  • 2 tablespoons Flaxseed flour/ground flaxseed
  • 4 tablespoons psyllium husk powder
  • 5 eggs separated
  • 2 tablespoons apple cider vinegar
  • 1 tablespoon baking powder
  • ½ teaspoon salt
  • 2 tablespoons olive or coconut oil
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 cup boiling water


  • Preheat the oven to 180C/350F degrees.
  • In a bowl add the coconut flour, ground flaxseed, psyllium husk powder, baking powder, salt and seasonings. Mix well.
  • In another bowl, whisk the egg whites until stiff.
  • Add the egg yolks to the coconut flour mixture and stir thoroughly.
  • Add the olive oil and mix well. Then stir in the apple cider vinegar.
  • Gently fold in the egg whites.
  • Add the boiling water and gently mix. If the mixture looks a bit too soft, let it sit for at least 10 minutes to firm up.
  • Split the mixture into 4 sections and take one section. Using your hands, make it into a sandwich sub shape.
  • Place on a baking tray lined with parchment paper, and repeat for the rest of the dough.
