Preparation

• Position a rack in the center of the oven and heat the oven to 375°F.
• Halve each eggplant lengthwise and place cut side up on a large rimmed baking sheet. Season the cut sides with salt and brush very generously with 4 Tbs. of the oil. Flip the eggplant over and roast, cut side down, until very soft, about 35 minutes. Set aside until cool enough to handle.
• Meanwhile, grate the cut sides of the tomatoes on the large holes of a box grater. Discard the skins. Drain the pulp in a fine-mesh sieve, stirring occasionally, until most of their liquid has strained through, about 20 minutes.
• Heat 3 Tbs. of the oil in a 12-inch skillet over medium heat. Add the onion and cook, stirring occasionally, until soft, about 5 minutes. Add the pepper, cauliflower, and garlic; cook, stirring occasionally, until the vegetables have softened somewhat, another 5 minutes. Remove from the heat. Stir in the tomato pulp, parsley, and oregano, and season to taste with pepper and salt. Stir in the feta.
• Using a spatula, flip the eggplant over. With a slotted spoon, divide the filling among the eggplant, using the spoon to gently push the filling into the flesh. Drizzle with the remaining 3 Tbs. oil and bake until hot, about 10 minutes. Sprinkle with more crumbled feta and parsley, and serve.
