A.1. Original Sauce Recipe Contest Entry. We had this incredible appetizer on vacation this summer that combined creamy polenta with a savory sauce. My husband didn't think he'd like it at all but loved it - and he loves this entree version featuring ground turkey in a sauce that highlights A1, served over the creamy polenta with mascarpone and fresh corn. The tangy sauce is a great pairing with the rich polenta - making for a very satisfying dish!
