Pulse almond flour, macadamias, and coconut flour in a food processor until well ground

Pulse in seeds, flaxmeal, and salt until almost fully ground (leave a little texture for crunch)

Pulse in shortening, then water until dough forms

Separate dough into two halves

Place each half of dough between two pieces of parchment paper

Roll out dough to ⅛-inch thick, then remove top piece of parchment paper

Transfer bottom piece of parchment paper with rolled out dough onto baking sheet

Cut into 2-inch squares using a pizza cutter or a knife

Bake at 300°F for 20 to 25 minutes (or dehydrate, haven't tried so you will need to experiment)

Serve
