Preheat the oven to 350 degrees Fahrenheit.

In a medium bowl mix together the almond flour, egg, onion powder and sea salt.

Fold in the Parmesan cheese.

Roll out on a parchment paper lined cookie sheet to about 1/16th of an inch thick.

Use a pizza cutter to cut the dough into 1 to 2 inch squares.

Bake at 350 degrees Fahrenheit for about 15 minutes, or until crisp and the edges just start to brown.
