Next, stir in tomatoes and vegetable broth, season with salt, pepper, and 1 TBSP of basil. Bring the pot to boil, then cover, and reduce heat to low. Allow the soup to simmer for at LEAST 20 mins, but the longer the better, you can leave it simmering for a couple hours for more flavor.
After your soup has simmered, carefully transfer it into a blender, or you can use an immersion blender inside the pot and blent the soup until desired consistency is reached.
