Preheat oven to 300°F. Since this recipe requires two baking sheets, set one oven rack to upper middle and one to lower middle.
In a large mixing bowl, combine cereal, breadsticks and pretzels.
In a small saucepan, over medium heat, combine butter, Dry Ranch Dip, Worcestershire sauce, hot sauce, seasoning salt, garlic powder and black pepper. Whisk well and cook until butter melts. Remove from heat.
Stir well and pour butter mixture over the cereal mixture. Stir until all dry ingredients are thoroughly coated.
Spread half of the cereal mixture, in an even layer, onto a baking sheet. Pour the remaining half over the second baking sheet.
Place baking sheets in the 300°F oven and cook a total of 30 minutes. After 15 minutes, add half the Gardetto Rye Chips to each tray and stir.
Rotate the baking sheets, top-to-bottom and front-to-back. Bake another 15 minutes. If the cereal isn't crispy, bake another 5-15 minutes.
Pour the baked mix onto a clean dishcloth to cool.
Store in an airtight container.
Enjoy!
