I received a jar of basil pesto as a gift, and am unfamiliar with how to use it, as it's not something in my regular cooking repertoire. Can someone educate me on how it's used and served? I can only guess--Do you dot it on a finished baked chicken? Marinate meats with it? Use it like a spread on toasted bread? I'm really not sure. Please provide ideas, or else it will be sitting unused in my fridge.
