How to make Keto Sub Rolls
  1. Preheat your oven to 175C/390F. Line a cookie sheet with parchment paper and set aside.
  2. In a mixing bowl, add the dry ingredients and mix well. Set aside.
  3. Add the egg whites to a large mixing bowl and beat with your hand mixer until foamy.
  4. Add the vinegar and water and continue mixing.
  5. While continuously mixing, pour ½ a cup of the dry ingredients into the bowl, followed by the rest.
  6. Stop the mixer as soon as it comes together and give a quick stir with a spatula.
  7. Leave to sit for about 5 minutes so that the dry ingredients can soak up the liquids.
  8. Once the dough feels firmer and sticky, spoon out onto a piece of parchment and shape into a thick rectangle.
  9. Cut into 4 evenly sized rectangles and place onto your prepared cookie sheet.
  10. Gently round the edges and cut 3 deep slices in the tops of each bun.
  11. Bake for 20-25 minutes until the buns are golden brown and sound hollow when tapped on the base.
  12. Leave to cool completely before slicing (if sliced hot they will deflate).
