Makes 4 servings
Ingredients
- 1/4 cup extra-virgin olive oil
 - 1 red onion, finely diced
 - 8 cloves garlic, finely minced
 - 2 teaspoons ground cumin
 - 1 tablespoon Aleppo pepper, or other mild chile flake
 - 2 teaspoons salt
 - 1/4 cup Balsamic Vinegar of Modena P.G.I.
 - 1 (28 oz) can San Marzano tomatoes, diced
 - 2 tablespoons fresh dill, roughly chopped
 
- 16 to 24 large prawns, peeled and deveined
 - 6 oz feta, crumbled
 - Pinch of chile flakes
 - Balsamic Vinegar of Modena, P.G.I., for drizzling
 - 2 baguettes or other rustic loaf, cut in half lengthwise
 - Olive oil, as needed
 - Dill sprigs, for garnish
 
Directions
- Heat the oil in a medium saucepan over moderate heat. Add the onion and cook, stirring occasionally, until translucent, about 8 minutes. Add the garlic, and cook until aromatic, about 1 minute. Add the cumin and Aleppo pepper, and cook until fragrant, about 1 minute more.
 - Add the vinegar and tomatoes. Bring to a simmer and cool until thickened and flavorful, about 15 minutes. Stir in the chopped dill.
 - Preheat the oven to 450°F.
 - Spoon about 3/4 of the tomato sauce into an oven-safe casserole dish or four individual gratin dishes.
 - Lay the prawns on the tomato sauce. Spoon the remaining sauce over and around the prawns, and top with feta, chile flakes, and a drizzle of vinegar and a drizzle of oil.
 - Bake until the mixture is bubbling and the prawns are cooked through, about 15 minutes.
 - Meanwhile, brush the baguette liberally with olive oil and sprinkle lightly with sauce. Broil or grill the bread until it is crisp and deep golden brown.
 - Sprinkle the prawns with the dill sprigs and serve with the toasted bread for scooping.
