Combine oats, flax seed meal, pumpkin seeds, and nuts in a large bowl and set aside.

In a sauce pan, bring salt, brown sugar, maple syrup, vegetable oil, and cinnamon to a boil.

Remove from heat and add vanilla. Pour the boiled mixture into the dry ingredients and mix well to combine.

Transfer to a foil-lined baking sheet and spread into an even layer.

Bake for 20 min at 325°F, mixing halfway.

Let cool completely before breaking it up with your hands and transferring to an airtight container.
