Position a rack in the middle of the oven and pre-heat the oven to 250ºF. In a shallow 3 quart baking dish, melt together the butter, hot pepper sauce, Worcestershire sauce, chili powder and oregano.
In a large bowl stir together everything else. Add the Frito mixture to the melted butter mixture and toss to coat and put in a baking dish. Return the dish to the oven and bake stirring every 10 minutes for 1 hour. The Trash should be dry, lose and lightly browned.
Transfer to a storage container, cool and cover tightly. Store at room temperature. The texture and flavor of the Texas Trash will be at their best when it is consumed within 48 hours.
