Preheat your oven to 375 degrees.
In a small bowl, whisk the ground chia seeds with 4 tablespoons of water to create a chia egg. Set aside for 3-5 minutes to thicken.
1 1/2 tablespoons ground chia seeds, 4 tablespoons Water (plus more as needed)
In another bowl, stir together the almond flour, tapioca starch, salt, and spices.
1 1/2 cups almond flour, 3/4 cup tapioca starch, 2 teaspoons dried rosemary, 2 teaspoons salt, 1 teaspoon garlic powder, 1/2 teaspoon onion powder
Add the chia egg and 1 teaspoon of water to the dry ingredients and mix well.
Continue adding 1/2 teaspoon of water at a time until the dough comes together nicely but isn't yet sticky.
On a large piece of parchment paper about the size of your baking sheet, roll the dough out very thinly, about 1/16" thick.
Use a pizza cutter to cut the dough into small squares, about 2" x 2".
Place the dough (still on the parchment paper) on a large baking sheet and bake for 18 minutes, or until the edges are just beginning to turn golden.
Let the crackers cool completely before breaking apart and enjoying!
