Pesto Mashed Potatoes

Hello, Lovelies!

I was really struggling with a St. Patrick recipe this year. I don't know what it is... I knew I wanted to do something that could and would be eaten year round, but was festive enough for leprechauns. What I came up with is actually nothing particularly new in my recipe rotation. Mashed Potatoes! How much more festive can you get than potatoes? Well, how about green ones?
