How to Make It
Cook the fettuccine in a large stockpot of boiling salted water until al dente.
Meanwhile, in a medium saucepan, bring the cream to a boil. Simmer over low heat for 5 minutes, stirring often. Add in the country ham, stirring to separate the strips; add the nutmeg.
In a large saucepan, melt the butter in the olive oil over moderately high heat. Add the Swiss chard leaves by the handful and cook, stirring occasionally, until wilted, about 5 minutes. Add the garlic and shallots and cook for 2 minutes. Season with salt and pepper.
Drain the fettuccine and return it to the pot. Add the ham, cream, Swiss chard and Parmesan cheese and toss to mix. Season with salt and pepper and transfer to a large warmed bowl. Sprinkle with the chives and serve at once.
