Preheat oven at 450 degree Fahrenheit and prepare a cookie sheet by greasing it and placing a parchment paper on it.
In a mixing bowl combine the oat flour, oat bran, salt, baking powder and onion powder and mix with a spoon.
In a food processor combine turmeric, cheese and oil and whip it smooth.
Now spoon the cheese mixture into the flour and mix well with your hands.
Now gradually add water until a soft dough is formed. (Not runny, you should be able to roll it).
On the prepared cookie sheet directly roll the dough with rolling pin as thin as possible without breaking it too much. Now cut into desired shape and sizes. With a fork gently press in the middle of each cracker.
Now place the cookie sheet in the middle rack of the oven and let it bake for 25 minutes or until done.
Take it out of the oven. Let it cool and enjoy with cheese or any dip of your choice.
Notes
While rolling if you find the dough dry grease your hands with little oil.
Can be stored in an air tight container in the room temperature for 2-3 days.
