For the chipotle spice blend: Mix together the sugar, chipotle powder, coriander, cumin, lime zest, granulated garlic and 1 1/2 teaspoons salt in a small bowl and set aside.
For the nuts: Preheat the oven to 350 degrees F. Lightly coat a rimmed baking sheet with the oil.
Put the egg white in a large bowl and whisk until frothy. Add the cashews, macadamia, peanuts and walnuts and toss to coat. Add the spice blend and toss to coat.
Spread the nut mixture evenly on the prepared baking sheet and bake, stirring occasionally, until golden brown, 15 to 20 minutes. Let cool on the baking sheet, then stir in the popcorn, bacon and chilies and transfer to a large bowl to serve.
