Lightly toast the nuts and seeds (optional but recommended): Add almonds, walnuts, pistachios, pumpkin seeds, and sunflower seeds to a dry skillet over medium heat. Stir for 4–6 minutes until fragrant and just golden. Let them cool completely so the chocolate doesn’t melt.
Prep the add-ins: Chop the dried fruit and dark chocolate into even, bite-size pieces. Zest the orange if using.
Combine: In a large bowl, mix cooled nuts and seeds with toasted oats, dried fruit, dark chocolate, salt, cinnamon, and orange zest. Toss until everything looks evenly distributed.
Taste and adjust: Add a pinch more salt for contrast, more chocolate for richness, or extra oats for volume. Make it yours.
Portion: Scoop into snack-size containers or reusable bags for easy grab-and-go snacking.
