Preheat oven to 350º
In large, deep oven roaster, melt 1 stick of butter (the butter will melt quickly).
Once the butter is melted, add several tablespoons of Worchestershire and several tablespoons of Cajun or Spicy Seasoning Salt right into the melted butter.
Stir butter mixture to combine seasonings and Worchestershire.
Add in about 1/2 box of each type of cereal.
Add pretzels, goldfish and peanuts/cashews.
Stir to coat evenly.
Cook in oven for about :30 minutes, but continue to stir mixture every few minutes so that the coating is evenly distributed.
When coating is very dry on all of the cereal and other ingredients, take out of the oven (about :30 minutes). Line containers with a paper towel, then store party mix in containers or Holiday tins.
