Preheat your smoker to 275 - 300 degrees. Cut the potatoes into bite sized chunks and toss in a bowl with parsley, garlic, olive oil, and a sprinkle of salt and pepper. Spread the potatoes out on a foil lined baking sheet. Add cherry chips to your smoker once preheated and smoke the potatoes for 1 hour.
Preheat your oven to 450 degrees and remove the potatoes from the smoker. Sprinkle two tbsp on ranch seasoning on the potatoes and roast them in the oven for 25 minutes.
Let them cool at room temperature or in the fridge for at least 30 minutes, up to 1 hour. In a large bowl, combine potatoes and the rest of the ingredients and mix well. Serve cold.
