Preheat your oven to 325 degrees and line 1 or 2 baking sheets (depending on their size) with parchment paper.
In a large bowl, mix the nuts, almonds and pumpkin seeds. Set aside.
In a small bowl, combine the coconut oil, maple syrup and vanilla extract. Pour over the nuts and mix well. Add the optional pumpkin pie spice and mix again, till everything is evenly coated.
Spread the nuts on the baking sheet(s) and sprinkle salt over the top of the mixture. Bake for 15 minutes.
Remove from the oven and stir the nuts to make sure they toast evenly. Bake for another 15 minutes and remove from the oven. Stir again, adding the coconut flakes. Bake for another 10 minutes to toast the coconut.
Remove from the oven for a final time, and let cool. Mix in the berries and store in an airtight container.
