Preheat the oven to 375F / 190C / 170 fan.
Place all the dry ingredients in a mixing bowl and stir to combine.
Add the egg and egg whites. Whisk to combine using an electric whisk with bread paddles. Add the boiled water and whisk again until like a slightly sticky dough. Allow to stand for 5 minutes.
Roll into 6 loaves about 4-5 inches in length and 1/2 inch in height and pat slightly to form. If the dough is sticking to your hands (it should be slightly sticky) simply wet your hands with a little water.
Place on a non-stick baking tray lined with parchment paper with enough space between them to grow in the oven.Bake for about 40 minutes until golden.
Remove from the oven and allow to cool then slice and spread on garlic butter. Broil 1-2 minutes until crispy, top with grated parmesan if desired and enjoy!
