Preheat the oven to 350 degrees Fahrenheit.
In a medium-sized bowl, combine all dry ingredients and mix until evenly combined.
Make a well in the middle of the dry bowl and add the soaked flaxseed, along with the apple cider vinegar and egg. Whisk all ingredients together well with a fork until a dough forms. Then use your hands to knead it for about 1-2 minutes. Put in the fridge for 10 minutes to rest.
Line a baking sheet with parchment paper. Divide the dough into 6-8 pieces. Brush with a little olive oil. Then, roll each into a long, evenly sized stick. Bake for 10-13 minutes.
