Creamy Chicken Marinara

For some reason, any time I’m trying to come up with a quick dinner idea my mind always instantly goes to something that involves tomato sauce. Maybe it’s because I know that’s one flavor that will always be a hit with the kids. Who knows? But whatever the reason, one thing I know for sure is that tomato sauce and diced tomatoes are probably two of the most common ingredients on this blog.

This dish evolved as it cooked. I originally was just planning to slow cook some chicken in a basic marinara sauce to serve over spaghetti. That’s a stand-by in our house on busy days. As dinner time was getting closer though, I knew I wanted to mix things up a little bit. So I improvised and tossed in a few extra ingredients that sounded good and ended up with something much better than the original. I just love it when that happens!
