Line two rimmed baking sheets with parchment paper.

Combine walnuts, pretzels, Chex cereal and oyster crackers in a large mixing bowl.

Simmer the butter, honey, Dijon, Worcestershire and spices in a small saucepan over medium heat until fully melted and bubbling.

Toss the sauce over the nut/pretzel mixture gently until everything is evenly coated.

Bake for 1 hour at 250 degrees, making sure to stir the mixture every 20 minutes to ensure even roasting and to prevent burning.

Cool completely before serving to ensure the mix gets a great crunch.  It will stay fresh in an airtight container for up to a week.
