On a large baking sheet with parchment paper, place zucchini and bell peppers, sprinkle lightly with oil, salt and pepper. Roast at 400 degrees F (convect/fan) for 15 min, stir, cook another 10 min but careful not to burn.
Meanwhile, make marinara sauce. In medium saucepan over medium heat, add oil, eggplant and onions. Cook for approx 15 min partially covered, stirring periodically, until the vegetables are softened and browning a bit.
Add garlic, cook another minute. Add cherry tomatoes, cook 3 min. Add the dried seasonings and crushed tomatoes, and simmer gently, covered, for 10 min.
Combine roasted vegetables and chickpeas with just enough sauce to have a chunky stew consistency.
Top with toasted panko breadcrumbs and fresh parsley/basil.
Serve with brown rice if desired (or pasta, and salad as another suggestion).
