In a small bowl, whisk together the dry seasonings.
Add the oil and whisk a few minutes, until the seasonings are mostly dissolved.
Place pretzels in a gallon (or larger) resealable plastic bag. Pour in the seasoning. Shake well but carefully. Shake every 30 minutes to evenly coat. Allow snack mix to marinate approximately 2 hours before serving. Store in the bag or an airtight container.
