A splash of Horizon Organic Milk for serving, if desired
Preheat oven to 325°F.
Combine almond butter, oil, maple syrup, orange zest and juice, and vanilla in a bowl; stir until smooth.
In a separate bowl, combine oats, cashews, walnuts, pumpkin seeds, cinnamon, and salt; stir well. Pour almond butter mixture into oat mixture; stir until all dry ingredients are well-coated. Spread mixture in an even layer on a rimmed baking sheet; gently press with a rubber spatula.
Bake for 15 minutes. Remove from oven and stir granola; press back in an even layer. Bake for another 15 minutes, or until golden. Remove from oven and let cool completely before breaking into chunks (at least 30 minutes).
