I know I'm too late, but my favorite Italian vegetable is rapini (aka broccoli rabe, Chinese broccoli, or Italian broccoli). It's very bitter, so not everyone likes it, but I just love it.
Toast some pine nuts, mince some garlic, cut the rapini into 3 inch long sections, blanch the rapini in boiling water, put some extra virgin olive oil in a pan, sautee the garlic and broccoli, add some salt, pepper, and red pepper flakes, squeeze half a lemon on top, and serve mixed with the toasted pine nuts.
