How to Make It
Preheat oven to 275°F. Line a rimmed baking sheet with parchment paper, and coat with cooking spray.
Whisk together butter, hot sauce, brown sugar, egg whites, Old Bay, and oregano in a large bowl. Add crackers and pecans; gently toss to coat. Spread mixture in an even layer on prepared baking sheet. Bake in preheated oven until mixture is tacky but not moist, 25 to 30 minutes, stirring every 10 minutes.
Transfer baking sheet to a wire rack; cool mixture completely, about 20 minutes.
Transfer mixture to a bowl. If using, add dried sausage; toss to combine.
