Peel strips on the eggplant and slice it into 1 1/2 inch cubes. Place them in a colander and toss them with 2 teaspoons kosher salt. Let them sit for 30 minutes to "sweat".
Meanwhile, preheat the oven to 425 degrees F and coat a baking sheet with nonstick spray. Rinse the eggplant cubes and toss them with 2 tablespoons olive oil. Arrange them on the baking sheet in one layer and roast in the oven for 30 minutes. Flip them halfway through to make sure they roast evenly on all sides.
While the eggplant is roasting, heat the remaining 2 tablespoons of olive oil in a Dutch oven or a pot over medium heat. Saute the onion for 10 minutes until golden. Add in the minced garlic, Italian green pepper and red bell pepper and cook for 10 more minutes.
Add the tomato paste, parsley, oregano, Aleppo pepper, 1 teaspoon kosher salt, black pepper and cumin to the vegetables and stir to combine. Add in the chickpeas and the diced tomatoes and give it a good stir.
Once the eggplant is roasted, add it to the chickpeas followed by 1/2 cup water. Turn the heat up to medium high and bring the stew to a simmer. Turn the heat to medium, cover and simmer for 15 minutes. Turn the heat off and let the stew sit covered for 10 minutes.
Serve warm with your favorite side dish.
