Combine almond flour, hemp hearts, egg and sea salt in a food processor. Blend on low until well mixed (15-30 seconds).
The dough is enough to fill 2 baking sheets. Approximately split the dough into 2 equal parts.
Spray 3 sheets of parchment paper with oil spray.
Roll 1/2 the dough out between 2 pieces of parchment paper very thinly.
Remove top parchment paper and slide the bottom paper (with rolled dough) onto a baking sheet.
Using a sharp knife or (preferably) a pizza cutter, cut dough into 1 inch (or bigger) squares.
Repeat the steps with the remaining dough and 2 remaining parchment papers (reuse one from the first round).
(Optional) Sprinkle with Everything But The Bagel Seasoning.
Bake for 12-14 minutes or until lightly golden brown.
Let cool and store in an airtight container.
Notes
Serving size is for 5 chips. Obviously you will probably eat more than that, but I can't presume how many. Therefore, you can calculate it based on how many groups of you eat!
