Herbed Cheese-and-Cracker Bits

My boys love these! My grandma use to make these around Christmas time every year.

1/2 cup vegetable oil
1 1-ounce package Hidden Valley Original Ranch salad dressing mix
2 10 1/2-ounce boxes Ritz Cheese Bits (not peanut butter flavor)
1 heaping tablespoon dried dill
1 teaspoon garlic powder
1 teaspoon celery salt

Place the crackers in a large sealable freezer container. In a bowl, mix the oil, salad dressing mix, dill, garlic powder, and celery salt. Pour this mixture over the crackers, cover the container, and invert it to coat the crackers with seasoning. Refrigerate for at least 24 hours, turning the container every so often to keep the crackers coated. Let the mixture come to room temperature before serving.
