How to Make It
Preheat the oven to 450°. Using a toothpick, pierce the eggplants all over. Place the eggplants on a rimmed baking sheet and brush with olive oil. Roast for 30 minutes, turning once, until the skin has blackened and the eggplants are tender. Slit one side of the eggplant and transfer to a colander to drain; let cool completely. Peel the eggplants, discard the seeds and cut into 1/2-inch dice.
In the bowl of a food processor, combine the scallions with the garlic, oregano and 1 cup of the parsley and pulse until finely chopped. Add the vinegar, lemon juice and the 1/3 cup of olive oil and puree until smooth. Season the dressing with salt and pepper.
In a serving bowl, toss the diced eggplant with the tomatoes, capers and the remaining 1 cup of parsley. Add the dressing and toss again. Season with salt and pepper and serve with toasted pita bread.
