Preheat the oven to 400 degrees F (204 degrees C).

In a large bowl, combine the flaxseed meal, whole flaxseeds, sea salt, and black pepper. Optionally, add Italian seasoning and garlic powder for extra flavor.

Add water to the bowl and stir until a dough forms. The mixture should be sticky and hold together.

Between two pieces of lightly oiled parchment paper, roll out the dough into a thin rectangle, about 12 x 9 inches and 1/8 inch thick.

Carefully remove the top parchment paper. Use a knife to score the dough into 1.5-inch squares, creating a grid pattern.

Bake in the preheated oven for 18-20 minutes, or until the crackers are golden and crisp.

Let the crackers cool completely before breaking them apart at the scored lines.
