In a large soup pot, place a small amount of water and sauté the onion, celery, and carrot. Cook and stir over medium heat until the vegetables soften slightly, adding more water as necessary.
Add the potatoes, canned tomatoes, basil, and veggie stock.
Bring to a boil, reduce the heat, cover, and cook about 15 minutes.
Next add the zucchini and cauliflower and cook for an additional 10 minutes.
Add the peas, corn and soy sauce. Cook for another 10 minutes, or until vegetables are tender.
Season to taste and ENJOY!
