How to Make It
Preheat the oven to 425°. On a baking sheet, roast the eggplants, turning once, until they are very soft and blackened, about 1 hour. Let cool slightly.
Slash the eggplants lengthwise. Using a spoon, scoop the pulp into a strainer. Let drain for 10 minutes, shaking the strainer occasionally.
On a work surface, finely chop the parsley with the garlic. Transfer the eggplant pulp to a food processor and pulse until chopped. Add three-fourths of the parsley mixture, and season with salt and pepper and pulse just until blended. Transfer the eggplant to a bowl and stir in three-quarters of the feta. Sprinkle with the remaining parsley mixture and feta, drizzle with olive oil and serve.
