1In a large pot, heat a small amount of oil over medium heat.
Add the chopped onion and sauté until translucent, about 5 minutes.
Add the diced carrots, zucchini, potatoes, and chopped green beans to the pot. Cook for another 5 minutes, stirring occasionally.
Pour in the vegetable broth and bring the mixture to a boil.
Reduce the heat to a simmer and add the cooked kidney beans, salt, black pepper, and Italian seasoning.
Cover the pot and let the soup simmer for 20-25 minutes, or until the vegetables are tender.
Taste and adjust seasoning if necessary.
Serve hot and enjoy your Minestrone Soup!
