Preheat your oven to 250°F (120°C) and prepare a large baking sheet by lining it with parchment paper.

In a large mixing bowl, combine the cereal, mini pretzels, almonds, sunflower seeds, sesame sticks, and cheese crackers.

In a small bowl, mix the olive oil and ranch seasoning until well combined.

Drizzle the ranch seasoning mixture over the dry ingredients in the large bowl and toss until everything is evenly coated.

Spread the coated mixture onto the prepared baking sheet in an even layer.

Bake the mixture in the preheated oven for 45 minutes, stirring every 15 minutes to ensure even coating and crispiness.

Remove the baking sheet from the oven and let the trail mix cool completely before serving or storing.

Transfer the cooled trail mix to an airtight container for storage.
