Preheat the oven to 250°F and line a baking sheet with parchment paper.
In a large bowl, combine the oats, almond meal, pumpkin seeds, walnuts, coconut, flax seeds, chia seeds, sesame seeds, vanilla, cinnamon, and cardamom.
In a blender, puree the soaked dates with the reserved soaking liquid.
Mix into the oat mixture to coat the oats thoroughly.
Spread onto the baking sheet and bake for about 1 ½ hours, until golden brown, stirring the mixture every 20 minutes or so to ensure even baking.
Let cool completely, then mix in the dried fruit.
Store in an airtight container at room temperature for 6 to 8 weeks.
