Author’s note: I like mashed potatoes as much as the next person, but since I no longer add unhealthy fats to my foods, I have looked for other ways to make my mashed potatoes creamy. Adding vegetables like parsnips is one of my favorite ways. They look like white carrots but have a mild tang that elevates an otherwise plain potato. If you don’t like parsnips, carrots or other root vegetables work just as well.
