Tips for the Best Cheese Tortellini Soup

- Add More Veggies: Toss in spinach, zucchini, or bell peppers for extra nutrients and texture.
- Adjust the Broth: Depending on the thickness of your spaghetti sauce, you may need to add more broth or water to achieve your desired consistency.
- Enhance the Flavor: A sprinkle of Parmesan cheese or a dash of Italian seasoning can elevate the taste even more.
- Meal Prep Friendly: This soup stores well in the fridge for up to 3 days, making it a great make-ahead meal.
