Position a rack in the center of your oven and preheat to 150°C (300°F). In a large mixing bowl, combine all the "Grain & Nut Base" ingredients except for the dried cherries and apricots. Stir until everything is evenly distributed.
In a separate smaller bowl, whisk together all the "Liquid Binding Syrup" ingredients the olive oil, maple syrup, honey, vanilla, and orange zest—until well emulsified. Pour this wet mixture over the dry oat base and toss thoroughly with a spatula to ensure every piece is lightly coated.
Spread the granola mixture onto a large, rimmed baking sheet in a single, even layer. Gently press down with the back of the spatula to encourage clumping. Bake for 45 minutes, carefully stirring the granola every 15 minutes to promote even toasting and prevent burning.
Remove the baking sheet from the oven and let the granola cool completely on the pan. Once cool, transfer the granola to a large bowl, add the chopped dried cherries and apricots, and toss to combine before storing in an airtight container.
