Preheat the oven to 425 degrees and line 2 sheet pans with parchment paper.* (see note)

Toss the eggplant with ½ cup olive oil, then spread out into an even layer on the sheet pans. Bake until golden brown, about 20-25 minutes, tossing once about half way through to ensure even browning. In the meantime, prep the rest of your ingredients. Transfer the browned eggplant to paper towels to drain, then sprinkle with salt.

Heat a medium-large pot or high-sided skillet over medium heat, then add the remaining 3 tablespoon olive oil and the onions and celery. Season with salt, then cook until just starting to lightly brown, about 10 minutes. Add garlic, cook for one minute more, then add tomato paste and water. Cook until the water has mostly evaporated and the tomato baste starts to caramelize. Add the tomatoes, then simmer for 10 minutes.

Add the olives, capers, vinegar, raisins and sugar, then cook until thickened, about another 15 minutes. Be sure to give it a stir every so often to prevent the bottom from burning. Turn off the heat, then add the eggplant, basil, parsley and pine nuts. Stir until everything is well combined, then taste and adjust seasoning as needed. Let cool to room temperature, then serve.

Leftovers can be stored in the refrigerator for up to a week.
