Preheat oven to 350 F. Combine oats, nuts, and seeds in a large bowl.
In a medium saucepan, combine salt, peanut butter, honey, flax oil, and brown sugar.
Bring to a boil over medium heat and immediately remove from heat. Pour over oats mixture and combine until dry ingredients are evenly coated.
Spray a muffin tin. Press a scoop of dough on the bottom, and up the sides of the muffin tin, forming a bowl.
Bake for 10-15 minutes or until starting to brown. Remove from oven. Using a spatula or knife, loosen granola bowl from the edges of the pan, without removing the granola bowl. Allow to cool for at least 2 hours, and then they can be removed.
