If you have prepared tortellini...
Put them in brodo, a clear Italian broth. Boil the tortellini in a large pot of salted water for 6 minutes; then add a bag of baby spinach and cook for another minute. Drain and then return the pasta and greens to the pot with 5 cups of chicken or vegetable broth and a small can (14.5 ounces) of chopped tomatoes; simmer 20 minutes. Serve sprinkled with grated Parmesan.
