Preheat oven to 350 degrees.
In a mixing bowl add ground flaxseed, sesame seeds and other seasoning if using.
Stir to combine, then pour in the water.
Use a spatula to combine all the ingredients, and allow to sit for a few minutes to absorb the liquid.
Take a 1/4 of the dough and place between two pieces of parchment paper. Use a rolling pin to roll about 2 mm thick. The thinner they are the crispier they will bake.
Carefully remove the top piece of parchment and bake for 5 minutes. Remove from oven and use a pizza cutter or knife to cut into desired shapes.
Place back into oven for 5 minutes, and then remove, separate the crackers and spread out on the cookie sheet.
Return to oven for another 5 minutes or so until they are as crisp as you would like them, without burning them!
Cool down on a cooling rack and enjoy at room temperature with your favourite dips or cheese.
Store in an airtight container in the fridge.
