Prepare mashed potatoes using the stove heating instructions as directed on the packaging. Once heated, stir in butter, cheese, and 1 tbsp of the pesto.
Transfer to a serving dish. Add the other 1 tbsp of pesto to the top of the potatoes. Using a spoon, gently stir to swirl throughout the potatoes. Garnish with more Parmesan if desired. Serve immediately and enjoy!
The Old Home Premium Mashed Potatoes can be found in the refrigerated dairy section of your local grocery store.
These re-heat well for leftovers too!
