Mix together seeds and seasoning in bowl, pour in water and stir to combine, allowing the seeds to absorb the water. Pour onto two cookie sheets lined with parchment paper and spread out to a rectangular shape, about ⅛ inch to ¼ in thickness. Sprinkle with a touch more salt.
Bake at 350 degrees for ~1 hour or until crisp. If they don't feel crisp after an hour, return to the oven for 5-10 minutes. Let cool (I left mine in the oven for a bit longer to cool done and harden) and break into pieces. Store in an airtight container.
Notes
Feel free to use any combination of seeds you want, as well as seasonings (cayenne or chili flakes, other dried herbs like thyme would also be good). The amount of salt you add might vary depending on if you use unsalted or salted seeds.
