Had to do some research on that "Jigg's Dinner." A site called MotherLindas offers the following:

A Jigg's Dinner is quintessential Newfoundland: It evokes memories of childhood, mom in the kitchen, and the population's Irish roots. Whether the name comes from the lively dance or the method used to catch the local cod (i.e., to "jigg" by jerking up quickly on a line), the feast is the same. Salted beef is soaked overnight and the cooked for a few hours in fresh . Next, a Newfoundland pudding bag, filled half full with yellow split peas is placed in the pot. After another hour, potatoes, turnips, and carrots are added to the brew. When done, the peas are removed from the muslin bag and whipped with black pepper and butter to a delectable mash.
