In a large bowl, combine the almond flour, salt and herbs.
In a small bowl, beat the egg well and then add the olive oil and beat a little more until combined.
Add the wet ingredients to the almond flour mixture and stir until thoroughly combined.
Gather the dough together and roll into a round disc. Place between two sheets of parchment paper and roll to 1/8" thickness.
Remove the top piece of parchment and transfer the bottom piece with the rolled out dough onto a baking sheet.
Cut dough into 2" squares with a knife or pizza cutter, or cut into whatever shapes you desire. Alternatively, you could bake the crackers whole and then break them into rustic pieces after they are baked and cooled.
Using a microplane grater, grate Parmesan all over the top of the crackers or simply sprinkle already grated Parm over the top.
Bake at 350 degrees for 20-25 minutes or until golden. Be sure and watch the crackers during the cooking process and rotate the baking sheet every 7 minutes or so to prevent hot spots.
Let the crackers cool on baking sheet for 30 minutes and then serve. I think your friends and family will be quite impressed knowing that they are eating homemade crackers...hey, I even impressed myself.
