Parmesan herb salad dressing

I recently bought a huge thing of buttermilk because it was the only size container available, which has forced me to get creative with how to use it all up. I decided to try making a creamy dressing at home and it was really delicious, much better than bottled dressing. I also used all low-fat ingredients here but use what you have on hand.

Ingredients:

1/2 cup buttermilk
2 rounded tablespoons mayo
1-2 rounded tablespoon(s) sour cream
1 clove garlic, made into a paste*
1 green onion, minced
1/2 teaspoon dill
1/8 teaspoon celery salt
1/2 teaspoon sugar
1/4 cup pamesan cheese
5-6 cracks black pepper
salt, to taste

Directions:

Mix buttermilk, mayo, and sour cream together until smooth. Add the rest of the ingredients and mix well, making sure to mix up the garlic paste well. Season with salt. Store in the fridge for at least 30 minutes before using to allow the flavors to come together.

*Make a garlic paste by mincing the garlic clove as finely as possible. Then sprinkle liberally with salt. Take the flat side of your knife and scrape the garlic and salt together several times until it forms a thick, smooth paste.
