This is more an American-Italian recipe than an Italian-American one. I found myself making this innovative dish, which always charmed our customers, quite a bit in the early 1970s. As simple a dish as this is, I have had requests for it in all my restaurants as far back as I can remember: I like the sauce a little feisty, so I'm generous with the crushed red pepper. You can add as much or as little as you like. Often, restaurant chefs finish this dish by swirling butter into the sauce at the end. You can do the same, or use olive oil to finish the sauce. I prefer olive oil, but I probably don't have to tell you that by now.
