Preheat oven to 325 degrees. In a large bowl, mix together oats, walnuts, pumpkin seeds, flax, protein powder, cinnamon, and salt. Drizzle in honey and olive oil then stir well to evenly coat mixture.
2 cups oats, 1 cup walnuts, 1/2 cup pumpkin seeds, 1/2 cup flax seed meal, 1/2 cup protein powder, 2 teaspoons cinnamon, 1/2 teaspoon salt, 1/3 cup honey, 1/3 cup extra virgin olive oil
Spread mixture in an even layer on a baking sheet and bake until golden, about 30 minutes (depending on how your oven runs I'd start watching at 20 minutes to prevent burning). Let cool completely before serving.
