Sear the Eggplant: Pat the eggplant cubes thoroughly dry with a paper towel. Heat 2 tablespoons of extra virgin olive oil in the Dutch oven over medium-high heat until shimmering. Working in two batches to avoid crowding the pan, sear the eggplant cubes for 2-3 minutes per side, until golden brown. Remove the seared eggplant to a plate and set aside.
Build the Aromatic Foundation: Reduce the heat to medium. Add the remaining 1 tablespoon of olive oil to the same pot. Add the chopped onion, bell pepper, carrot, zucchini, and celery. Sauté for 8-10 minutes, stirring occasionally, until the vegetables have softened and the onion is translucent. Stir in the sliced garlic and cook for one minute more until fragrant.
Bloom the Spices: Add the Ras el Hanout, cumin, coriander, smoked paprika, and cinnamon to the pot. Stir constantly for 45-60 seconds, allowing the spices to toast in the heat and release their aromatic oils.
Construct the Stew Base: Pour in the no-salt-added crushed tomatoes and the low-sodium vegetable broth. Scrape the bottom of the pot with a wooden spoon to deglaze, lifting any flavorful browned bits. Bring the mixture to a gentle simmer.
Braise for Tenderness: Gently return the seared eggplant cubes to the pot. Stir in the rinsed chickpeas, raisins, sea salt, and black pepper. Submerge everything in the liquid. Reduce the heat to low, cover the pot, and let it simmer for 25 minutes, or until the eggplant is completely tender and succulent.
Prepare the Whole-Grain Couscous: While the stew simmers, heat 1.5 tablespoons of olive oil in the medium saucepan over medium heat. Add the dry whole-wheat pearl couscous and toast for 2-3 minutes, stirring frequently, until it smells nutty. Stir in the turmeric, then add the water. Bring to a boil, then reduce heat to the lowest setting, cover, and cook for 10-12 minutes or until the liquid is absorbed. Remove from heat and let stand, covered, for 5 minutes.
Finish and Brighten: Uncover the stew. Squeeze in the fresh lemon juice and stir gently. Taste and adjust seasoning if necessary. The lemon juice should brighten all the flavors.
Serve: Fluff the cooked couscous with a fork. To serve, spoon a generous portion of couscous into a shallow bowl. Ladle the Aromatic Eggplant & Chickpea Stew over the top. Garnish lavishly with the fresh chopped parsley and mint before serving.
