Prepare the Vegetable Sauce: Heat the olive oil in a large saucepan over medium heat. Add the chopped onions and sauté for about 3 minutes, until softened. Add the bell peppers and sauté for another 2 minutes. Introduce the zucchini and sauté for 3 minutes. Finally, add the chopped tomatoes, tomato paste, minced garlic, oregano, basil, thyme, salt, and pepper. Cover the saucepan and let it simmer for 20-30 minutes, stirring occasionally, until the sauce has thickened slightly. (Total time: ~30-40 minutes)
