In just over 30 minutes, you can make homemade Spaghetti Minestrone. This hearty soup can easily be made ahead of time. Just warm on the stove before serving on busy weeknights.
Warm oil in a large pot over medium-high heat. Add carrot, onion and celery; cook, stirring often, until softened, 3 to 5 minutes. Add garlic; sauté 1 minute. Pour in broth, increase heat to high and bring to boil. Add both types of beans. Cover, reduce heat to low and simmer 5 minutes.
Add cauliflower, spaghetti, zucchini and tomatoes. Cook until vegetables are tender, about 8 minutes. Add parsley; season with salt and pepper. Garnish with Parmesan.
