Preheat oven to 350.
In a medium bowl, whisk oil with dressing mix and spices.
Place 1/2 of the pretzels in a large bowl.
Pour 1/3 of the oil mixture over pretzels and stir until pretzels are well coated.
Place the other half of the pretzels in the bowl and add another 1/3 of the oil mixture, stir until pretzels are well coated.
Add the last of the oil mixture and stir again.
Spread out pretzels on a very large sheet pan or two smaller ones.
Bake at 350 for 5 minutes - toss pretzels well - bake an additional 3 minutes.
Let cool for 15 minutes. Store in an airtight container.
