When you want to put on a bit of a show while essentially putting forth the amount of effort typically associated with grilling a burger, reach for branzino. This beautiful, saltwater fish, also known as European sea bass, is flaky and slightly sweet. It holds up beautifully when grilled whole. Have your fishmonger do the dirty work of gutting and scaling, and put your effort into complementing this beautiful whole fish with parsley and a summery lemon gremolata topping.
