In a medium bowl, combine almond flour, salt, garlic powder, chipotle powder and chia seeds.
Gently fold in Greek yogurt. Dough will be a bit crumbly.
Transfer dough to one side of a large piece of parchment paper.
Press dough into an even thickness. Place another piece of parchment on top of the dough. Use a rolling pin to roll dough out evenly to a 1/8" thickness. Remove top piece of parchment.
Using a knife or pizza cutter, cut dough into small squares.
Transfer parchment and dough to a cookie sheet. Bake for 45-50 minutes or until crackers are golden brown on top and firm to the touch. Thinner crackers will not take as long to bake. Start checking on the crackers after the first 30 minutes to avoid over-baking.
Remove from oven and allow to cool.
Notes
Because these crackers have no preservatives, they are best if eaten within a couple days. That's not a problem though ... they won't last that long!
