How to Make It
Preheat oven to 325°F. Whisk together oil, onion, tomato paste, garlic powder, Worcestershire, oregano, vinegar, salt, and pepper in a large bowl. Add pretzels and toss evenly to coat. Transfer to 2 rimmed baking sheets and bake, stirring halfway through and rotating sheets, until golden and fragrant, 15 to 20 minutes. Let cool completely. Pretzels will keep in an airtight container at room temperature for up to 1 week.
