Heat the oven to 450°F with a rack in the middle position. Line a rimmed baking sheet with kitchen parchment. In a large bowl, toss together the tomatoes, onion and ½ teaspoon each salt and pepper; set aside. With a rolling pin, roll the pastry into a 10-by-14-inch rectangle, then place on the prepared baking sheet. Using a paring knife, score a 1-inch frame around the edge of the pastry, then poke holes in the pastry with a fork, avoiding the border. Spread the mustard on the pastry, avoiding the border, then sprinkle with the cheese.

Using a slotted spoon, distribute the tomato-onion mixture in an even layer on top; discard the liquid remaining in the bowl. Sprinkle with the olives and drizzle with the oil. Bake until the pastry is golden brown, 15 to 20 minutes. Cool for 5 to 10 minutes before slicing. Serve drizzled with additional oil.

Chopped fresh oregano OR torn fresh basil OR chopped drained capers OR a combination
