To be Italian is to appreciate dark leafy vegetables, especially broccoli rabe, an earthy bitter brassica that pairs beautifully with bold ingredients like sausage, anchovy and hot pepper. Dark leafy greens are nutrition superstars, providing plenty of vitamins A, C and K as well as heart-healthy fiber and cancer-fighting antioxidants. Include a generous portion of rich dark leafy greens, such as chard, kale, escarole and collards, either in a salad or sautéed with olive oil, plenty of garlic and a touch of crushed red pepper.
