Ingredients

  • 1/2 cup all-purpose flour
  • 1/2 cup whole wheat flour
  • 1/4 teaspoon salt
  • 1/2 teaspoon freshly ground black pepper
  • 2 cups freshly ground Parmesan chese
  • 1/2 cup unsalted butter, chilled and diced
  • 2 to 3 tablespoons ice cold water
  • 1 1/2 cups mozzarella cheese, grated
  • 6 mixed-color heirloom tomatoes, washed and sliced 1/4-inch thick
  • 1/4 cup fresh basil, roughly chopped
  • 1 tablespoon fresh oregano, chopped
  • 3 tablespoons scallion greens, chopped
  • 2 tablespoons olive oil

Method

  • Preheat the oven to 375F.
  • To make the crust: Put the flours, salt, pepper, Parmesan and butter in a food processor.
  • Pulse until the mixture resembles coarse meal.
  • With the motor running, drizzle in the water until the dough starts to stick together.
  • Press the dough into a 9- to 10-inch tart pan with a removable bottom.
  • Place in the refrigerator for about 15 minutes.
  • Prick the bottom of the crust all over with a fork.
  • Line with parchment paper and then fill with pie weights or dried beans.
  • Bake in the center of the oven for about 15 minutes.
  • Remove the parchment and weights, and return the pastry shell to the oven to bake until golden, 15 minutes longer.
  • Let cool completely.
  • Reduce oven to 350F.
  • To make the filling: Sprinkle one-third of the mozzarella over the bottom of the pastry shell.
  • Arrange one-third of the tomato slices on top of the cheese.
  • Sprinkle with one-third of the basil, oregano, and scallion greens.
  • Repeat this step two more times, then drizzle with the oil.
  • Bake until the mozzarella has melted, 15 to 20 minutes, and serve hot or at room temperature on fresh baby arugula with grape tomatoes.
