Pour the olive oil into a large saucepan and heat over medium heat. Add the garlic and toss lightly in the oil until barely browned. Add the carrots, zucchini, onion, and peppers, and continue heating for 3 to 4 minutes, or until onion begins to soften. Stir in the kale and continue cooking until the kale wilts and the volume is reduced. Add the tomatoes, salt, and pepper, heat the mixture until bubbly, and then cover and simmer on low heat for 45 minutes.
