I make this Cheesy Mix all the time. It's a great change from the typical Chex Mix and the whole family loves it. It disappears pretty fast. That sprinkle of Parmesan at the end just tops it off perfectly.
3 cups Cheez-It original
3 cups Cheez-It grooves, Zesty Cheddar Ranch
2 cups pretzels
2 cups corn or rice Chex
1 cup cashews
6 tablespoons butter, melted
¼ cup Worcestershire sauce
2 tablespoons Ranch seasoning mix
1/3 cup Parmesan cheese
Mix cereals, crackers, cashews and pretzels in roaster. Whisk together butter, sauce and seasoning. Pour over snack mix. Stir. Bake at 250 degrees for 1 hour stirring every 15 minutes. Spread on foilr to cool. Sprinkle evenly with Parmesan cheese.
