Crispy "Everything" Flatbreads
Substitute any whole grain flour for the spelt flour and 1/2 teaspoon fine salt for kosher salt if desired.
Garlic/onion powder and granulated garlic/onion are the same thing, just ground to a different fineness, and they're interchangeable. Just make sure they're made with pure garlic and onion, and not a bunch of salt. Feel free to try this with freshly minced garlic and onions as well.
For a more rustic look, you can bake these uncut, and then once cooled, snap them into irregular shards.
