12-16 oz. plain oyster crackers
1 pkg. Hidden Valley Ranch buttermilk dressing mix
1/2 tsp. dill weed
1/4 tsp. garlic powder
3/4 to 1 c. salad oil

I also sometimes use fresh garlic, crushed, in place of powder.

Combine all with oil. Pour over crackers and stir well to coat. Place in warm oven for 20 minutes at 250 degrees.
