Ingredients
3 tablespoons coarsely chopped fresh flat-leaf parsley
2 tablespoons coarsely chopped fresh oregano, plus sprigs for garnish
1 tablespoon coarsely chopped fresh thyme
1 garlic clove, minced
1/4 cup extra-virgin olive oil
Coarse salt and freshly ground pepper
2 small zucchini, cut into 1/8-inch-thick rounds
2 small yellow summer squash, cut into 1/8-inch-thick rounds
6 sheets phyllo dough (each 12 by 17 inches), thawed if frozen
3 tablespoons unsalted butter, melted
1/2 cup pitted Kalamata olives
Preparation
Preheat oven to 375 degrees. Stir together herbs, garlic, and 3 tablespoons oil; season with salt and pepper. Toss zucchini and squash with 1 tablespoon oil in a separate bowl; season with salt and pepper.
Unfold dough; cover each sheet with a clean, slightly damp kitchen towel. Brush a rimmed baking sheet with butter. Press 1 sheet of dough into baking sheet. Lightly brush dough with butter. Repeat, layering remaining 5 sheets dough and brushing each with butter.
Spread herb mixture over dough. Spread zucchini and squash on top; top with olives. Bake until edges are browned, 25 to 30 minutes. Let cool slightly. Cut into 6 pieces; garnish with oregano.
