This dish originally made a splash in my cookbook Potluck and let me tell you, it's a dish worth making the next time you need a hearty breakfast casserole that feeds a crowd. If you cannot find linguica sausage, simply substitute any smoked pork sausage that you like.
Easy to over salt this one since the pancetta will simmer throughout. Salt lightly and use Essence judiciously along the way, then enjoy. This would be great as a brunch side dish, just cook a few eggs right before serving.
