In a large soup pot, sauté diced carrots, onions, and celery in oil over medium-low heat for about 5 to 7 minutes or until onions are just turning translucent. (Or use this method to sauté without oil.)
Add garlic sauté for one more minute.
Meanwhile, scrub potatoes. Dice into 3/4-inch pieces.
Turn heat to high. Add 1/2 cup water, potatoes, green beans, corn, and seasonings. Cover and bring to a boil.
Reduce heat and cook at a very low and gentle boil, stirring often, for 12 to 14 minutes or until potatoes are tender.
Stir in milk. Cook over low heat until hot, but do not boil. Add salt to taste.Serve hot.
Notes
1. I recommend soy, almond, or cashew milk in this recipe. The exact amount of milk you use depends on how you like your soup.2. This soup does not reheat well. If you need to make it ahead of time, reheat it very gently and slowly.
