1 ½ tablespoons salt-free seasoning blend (such as Mrs. Dash® Table Blend)
1 ½ tablespoons dried dill weed
½ teaspoon cayenne pepper
1 (1 ounce) package dry ranch dressing mix (such as Hidden Valley Ranch®)
17 ½ ounces crunchy cheese puffs (such as Cheetos®)
15 ounces savory snack mix with toasted cereal (such as Chex® Mix)
15 ounces mini pretzels
12 ounces oyster crackers
Whisk oil, seasoning blend, dill, and cayenne together in a microwave-safe bowl. Microwave on medium (50%) power for 3 minutes; this helps the oil to become a little thinner and easier to cover snack mix. Whisk in ranch mix until blended.
Place cheese puffs, savory snack mix, pretzels, and oyster crackers into a large container or a large paper bag. Pour oil mixture in a little at a time, stirring to evenly distribute.
