In a large, wide deep skillet, heat 2 tablespoons oil over medium heat, and sauté the onions, garlic and peppers, until soft, about 7 minutes. Season with salt and pepper. Place in a separate bowl and set aside.
Add a little more of the oil to the skillet, return to the heat, and sauté the eggplant and zucchini, until soft, about 8 to 10 minutes. Return the cooked onion mixture to the skillet and add the tomato, oregano and basil and any remaining oil and stir in the stock. Reduce the heat to low, cover the pan and simmer, stirring occasionally, until the vegetables are very tender, about 25 to 30 minutes. Season with the lemon juice and more salt and pepper to taste. Toss in the chickpeas if using and heat through. Serve over cooked farro or rice, with Greek yogurt and lemon wedges on the side.
