Preheat the oven to 350° F.
Grease a baking sheet.
In a mixing bowl, combine buckwheat flour, water, and oil and mix well.
Add herbs, garlic, and salt, and mix well.
Knead on a counter floured with additional buckwheat flour until dough comes together and isn’t too sticky.
Roll or pat out dough into a 1/16” thick rectangle on the baking sheet.
Score into cracker-shaped squares with a pizza cutter.
Bake for about 15 minutes.
Separate out crackers and turn; bake for another 10-15 minutes, or until crisp.
