1 can or jar of Tomato puree  
1 box of Vegetable Broth
3 stalks of Celery  
1  small Onion  
2 cloves of Garlic  
3 Tomatoes  
1 cup of chopped baby Carrots
1 cup of cut Green beans (optional frozen)  
1 cup of Water Chestnuts (optional)
3 cups Water
Hot Sauce (optional)
Salt and Pepper to taste
(For a quick and easy soup, you can buy mixed frozen veggies)
1) Chop everything up small and evenly (so everything cooks evenly).
2) Heat a 1/4 cup of Broth in a large Sauce pan (optional Slow Cooker) on Medium high heat. Then add Onion, Garlic, Celery, Carrots, and Water chestnuts. Let that cook for a few minutes.
3) Then add the rest of the broth and vegetables. 
4) Add the water, puréed tomatoes, spices, and hot sauce.
5) Bring to a boil, then turn it down to simmer. Let it simmer for about an hour (the longer the better flavor).
