Buttery Herbed Polenta on the Traeger Grills Ranger

In a bowl, mix equal parts butter and olive oil with the all purpose rub. Take rounds of herbed polenta and shellack the butter-oil-rub mixture generously over them. Preheat your grill (like a Traeger Grills Ranger) to 350F (175C). Grill the polenta rounds until they are crispy on the outside and pillowy soft on the inside. Once grilled, top with grated Parmesan cheese and chopped scallions to finish.
