Add broth, tomatoes, onion soup mix, water and spices to pot. Simmer for at least 1 hour.
Add vegetables and rice to pot. Add more water if needed. Note the squash will break down so that you don't notice it in the soup, it just makes the broth creamier. It is a great way to get your kids to eat more veggies without them knowing!
Simmer an additional 1/2 hour to 40 minutes - until rice is cooked.
