Preheat oven to 250 degrees F. Line 2 large rimmed baking sheets with parchment.
In a very large bowl or pot, combine pretzels, crackers and pita chips. In a small bowl, whisk together butter, vinegar, Italian seasoning, garlic powder and onion powder. Season with pepper to taste. Drizzle over pretzel mixture. Toss until well coated.
Spread mixture on prepared sheets. Bake 1 hour, stirring every 15 minutes. Remove from oven and cool completely. Divide into gift bags or jars.
Tip: Party mix can be kept in an airtight container at room temperature for up to 5 days.
