Polenta Squares with Garlic Shrimp and Spinach Pesto

Yesterday I have received a postcard!

I haven’t received one in ages. I used to send them to our parents from places we were traveling to with a good thought. It was great! Why did I stop?

My brothers’ in law were in Rome for a couple of days and they wanted to let us know how much they would have loved us to be there with them. In a postcard. No text. No FaceTime. Just brings back those back to basic things. Sometimes we just speed too much through life and although I love this new social media part, it is so nice to receive a hand written postcard.

Just curious, do you still send/ receive postcards?

Polenta Squares with Garlic Shrimp (Prawn) and Spinach Pesto

This postcard brought back memories of beautiful places and treasured snippets from my Italian trips.  And, of course one of them is related to those unforgettable Italian feasts.

Talking about feasts, for today I made Polenta Squares with Garlic Shrimp and Spinach Pesto.

It cannot get more Italian than this.

Polenta Squares with Garlic Shrimp and Spinach Pesto

I made this appetizer inspired by the southern Italian Christmas Eve tradition known as the Feast of the Seven Fishes. Was really interesting reading about it.

Some believe that each fish represents a day of the week, but most traditions come from the observance of the Cena della Vigil (the dinner of the vigil), the wait for the birth of Christ in which early Christians fasted on Christmas Eve.

While the tradition is to eat 7 different fish, some households in southern Italy actually eat 9 or even 12 fish instead (for the apostles). The feast usually goes on for hours, with one fabulous seafood dish following another.

My Polenta Squares with Garlic Shrimp and Spinach Pesto would be the perfect start of the feast! It is really easy to make, as you can imagine and celebrates all Italian flavors in a small bite. You can make  polenta and spinach pesto the day before serving it. Just cook the shrimp before your guests arrive and you are set 🙂

Ohhh.... Interesting tradition. A seafood feast sounds lovely! These little bites look very fun to serve. And I think everyone would love shrimps as appetizer. Talk about postcard, I probably haven't sent one out since elementary school. When I first got the States, I received letters from my mom and friends all the time. I really miss those days. It is good to get unplug sometimes. Hard though, right?
