Preheat the oven to 275°F. Line a baking sheet with parchment paper or lightly greased foil.
Combine the dry ingredients: In a large mixing bowl, stir together the oats, flaxseed, quinoa, coconut, nuts, sunflower seeds, cinnamon, cardamom, and salt.
Mix the wet ingredients: In a small bowl, whisk the honey, olive oil, and vanilla extract until smooth.
Combine wet and dry ingredients: Pour the wet ingredients over the dry ingredients and mix until evenly coated.
Spread and bake: Spread the granola mixture evenly on the prepared baking sheet. Bake for 40-45 minutes, stirring halfway through, until golden brown and fragrant.
Cool and add mix-ins: Let the granola cool completely on the baking sheet. Stir in the dried cherries once cooled.
