In a roasting pan (or 2) Mix cereal, pretzels, nuts and cheese together stirring so it is well blended.
In a dish mix the oil, garlic powder, salt and W. Sauce. Continue mixing while pouring over your cereal mixture as this will all want to separate in the dish. Once mixture is poured over the cereal mixture, stir your cereal mixture so it is well coated.
Place roasting pans in the oven and bake at 250 F for 1h 40m stirring every 20 mins.
** For gift giving, have cleaned mason jars ready for once the bits & bites come out of the oven. While the bits and bites are still hot fill the mason jars, cover with the mason jar covers and set aside. The heat left in the bits & bites will vacuum seal the jars allowing you to store, or wrap up as the vacuum seal will keep your snack food fresh for gift giving
