Directions

  1. Preheat oven to 450, with racks in upper and lower thirds. Place tomatoes on a rimmed baking sheet. Sprinkle with 1 tablespoon oil, teaspoon tarragon, sugar, salt, and pepper; toss to coat. Arrange tomatoes cut side up. Roast on lower rack until tender, 20 to 25 minutes. (Keep oven on for fish.)
  2. Meanwhile, make sauce: In a small bowl, whisk together mayonnaise, remaining 1/2 teaspoon tarragon, and lemon juice; season with salt and pepper. Set aside.
  3. Line a rimmed baking sheet with aluminum foil and brush with oil. In a food processor, place bread, a pinch each salt and pepper, and remaining tablespoon oil; pulse until fine crumbs form.
  4. Lay fillets flat on prepared baking sheet; season with salt and pepper. Spread top sides with mustard; sprinkle with bread crumbs, pressing to adhere. Bake on upper rack until fish is cooked through and crumbs are browned, 6 to 8 minutes. Serve with tomatoes and sauce.
