Radicchio rosso à la Trevisana

Radicchio rosso alla Trevisana is a traditional dish originating from Treviso. It's made with a few simple ingredients – the red radicchio from Treviso (radicchio rosso di Treviso), olive oil, salt, and black pepper. The heads are cut into quarters, washed, dried, then placed in the grill pan. The radicchio is drizzled with olive oil and seasoned with salt and pepper, then cooked under the hot grill while being turned as it cooks so that it doesn't burn. The radicchio is served on a plate and the juices from the pan are spooned over it. Some cooks like to drizzle the grilled radicchio with a sweet and sour condiment called agrodolce. The dish can be served warm or cold, and if the red radicchio from Treviso is unavailable, it can be replaced with radicchio di Chioggia.
