Preheat oven to 300 degrees. In a large mixing bowl, combine cereals, cashews, and pretzels. In a small bowl, melt butter and add worcestershire, seasoning blend, garlic powder, onion powder, and hot sauce. Pour butter mixture over cereal mixture and toss to evenly coat. Spread mixture onto a sheet tray and bake for 20 minutes, stirring every 5 minutes.
