Brik is a traditional Tunisian dish consisting of brik pastry surrounding a savory filling and deep fried to golden perfection. This recipe draws inspiration from the Tunisian classic. Filled with mashed potatoes and sliced truffles, the pastry is rolled to look a bit like a spring roll and then baked until golden and crisp. These pastry parcels are lower in calories than their fried counterparts as they do not contain the additional fat from frying in oil. Phyllo dough can be substituted for brik pastry.
