Creamy Chicken, Tarragon and Peas with Cheesy Polenta

I’m going to lay my cards on the table straight away. This is a rich dish, but sometimes you just need a full-smack-in-the-face piece of comfort, and this is it. The peas keep things a little brighter and allow you to feel like you’re being good. And if you’re not keen on polenta, you can always serve this on a bed of rice or tossed through tagliatelle.
