Preheat your oven to 300°F (150°C).
In a large mixing bowl, combine Chex cereal, pretzel sticks, and nuts.
In a separate bowl, whisk together dill pickle juice, olive oil, garlic powder, onion powder, dill weed, and salt.
Pour the dill pickle mixture over the cereal mix and toss to coat evenly.
Spread the coated mix in an even layer on a baking sheet.
Bake for 30-35 minutes, stirring every 10 minutes.
Remove from the oven and let cool completely.
Once cooled, store in an airtight container.
