Preheat the oven to 325 degrees.
In a large bowl, stir together the peanuts, walnuts, and pistachio nuts. Set aside.
Zest the lime and measure out a tablespoon of lime juice. Place these ingredients in a small bowl and stir in the honey. Pour these wet ingredients over the nuts, and stir to coat evenly.
Combine the chili powder and the salt in a small bowl. Sprinkle these seasonings over the nuts, and stir again to evenly distribute the seasonings. Taste the nuts, and add extra seasonings if desired.
Transfer the nuts to a 9 by 13 inch baking pan (or similar). Roast them in the 325 degree oven for 15 minutes, stirring occasionally.
Cool completely before transferring the nuts to an airtight container for storage.
