What are your tips for elevating store bought marinara sauce?

[mikederoobs]

I want to make chicken parmesan tonight and I don’t have enough time to make homemade marinara sauce. I’ll be honest, I’ve never even made marinara sauce before. My boyfriend is half Italian, so I’m always a little self conscious when it comes to the quality of any pasta/italian dishes I make.
I’ll learn to make the sauce eventually, but for tonight and other times when I’m in a pinch, what can I do or add to store bought cans of marinara sauce to elevate them and make it taste a little more authentic?
