Preheat oven to 400 degrees.
In a small pan, sauté shallots and garlic in 1 tablespoon of olive oil until tender, about 3 minutes. Stir in mustard, and set aside.
Place pastry shell in a 9-inch pie dish. Layer in half of the tomatoes, and season with salt and pepper; spread shallot mixture over top. Add goat cheese and half of the basil, distributing evenly. Layer in remaining tomatoes, and season with salt and pepper. Drizzle 1 tablespoon each of olive oil and vinegar over the tomatoes; top with remaining basil.
In a small bowl, combine bread crumbs, remaining 2 tablespoons of olive oil, and Parmesan cheese. Sprinkle evenly over tomato filling.
Bake 30 minutes, or until topping and crust are golden brown.
