Preheat oven to 300°F. Spray a large baking sheet with nonstick cooking spray or line with parchment or Silpat. In a large bowl, stir together oats, walnuts, coconut, wheat germ, ground flax seed, cinnamon, nutmeg, and salt.
In separate small bowl, stir together brown sugar, canola oil, honey and vanilla.
Pour wet ingredients over dry ingredients and stir until everything is well coated.
Spread granola in an even layer over the baking sheet. Bake for 15 minutes, stir, and then bake for 15-20 minutes longer until golden brown.
