Heat the oven to 425°F. Lightly flour a work surface, lay the sheet of pastry out, and gently roll until it measures about 11 x 15 inches. Slide the pastry onto a baking sheet. Prick the pastry all over with a fork, at about 1-inch intervals.
Gently stir the anchovies into the ratatouille. Spread the ratatouille over the pastry, to within an inch of the the borders. Distribute the feta over the tart.
Bake in the heated oven until the pastry is puffed and browned (including on the bottom), 18 to 25 min. Slide onto a cutting board, sprinkle with the parsley, and cut into squares or strips. Serve warm or at room temperature.
