Add chicken broth, meatballs (we add them into the soup raw, without browning them. If you prefer to brown them, you can, but it's not necessary. Allowing them to cook into the soup adds some nice flavor!), crushed tomatoes, sugar water, basil, Italian seasoning, salt, black pepper, bay leaves, oregano and red pepper flakes. Stir and bring to a boil. Reduce heat to simmer and cook 30 minutes.
