Preheat your oven to 250°F (120°C). Line a baking sheet with parchment paper.

In a large mixing bowl, combine the rice Chex, corn Chex, pretzel twists, and bagel chips.

In a small saucepan, melt the butter over low heat, then stir in the dill pickle seasoning, garlic powder, onion powder, dill weed, and salt until blended.

Pour the butter and seasoning mixture over the Chex mix and toss to coat evenly.

Transfer the coated mix onto the prepared baking sheet in a single layer.

Bake for 45 minutes, stirring every 15 minutes.

Remove from the oven and allow to cool completely before storing.
