Add all of the ingredients to a jar or bowl. If using a jar, screw the lid on tightly and shake until the ingredients are incorporated. If using a bowl, whisk until the ingredients are incorporated. Give the dressing a quick shake or whisk just before serving.
*You can use one minced clove of fresh garlic in place of the garlic powder if you prefer a stronger garlic flavor.**Bottled grated Parmesan with cellulose (an anti-caking agent) may clump slightly, but will still taste great.
