Everyone knows tortellini make a quick weeknight pasta dinner—but they also add substance that turns this quick, colorful vegetable soup into a meal. One caveat: Read the label carefully; avoid pasta products made with hydrogenated oils or unnecessary preservatives. Enjoy this soup with a slice of multigrain baguette and a spinach salad.
Heat oil in a Dutch oven over medium heat. Add carrots and onion; stir, cover and cook, stirring occasionally, until the onion is soft and just beginning to brown, 6 to 7 minutes. Stir in garlic and rosemary and cook, stirring often, until fragrant, about 1 minute.
Stir in broth and zucchini; bring to a boil. Reduce heat to a simmer and cook, stirring occasionally, until the zucchini is beginning to soften, about 3 minutes. Add tortellini and tomatoes and simmer until the tortellini are plump and the tomatoes are beginning to break down, 6 to 10 minutes. Stir vinegar into the hot soup just before serving.
