Better hot than cold

I'm reaching the conclusion that most sandwiches taste better hot from the panini press than cold.
Case in point: today's prosciutto, mozzarella, fig jam and radicchio on Tuscan bread. It was a tasty cold sandwich (well, room temperature, actually) but it didn't hold a candle to the panini version. I thought adding the raddichio would liven it up a bit, but it wasn't a significant difference. The one thing it had going for it was the prosciutto. Now that's tastier cold than hot. Unless it's fried, of course. Mmmm...
