Okay, sweetie. So you know how sometimes we have soup for dinner when it's cold outside? Well, wedding soup is a kind of soup that is really special and yummy and lots of people like to eat it at fancy events like weddings.
It has a bunch of different ingredients, but the main ones are tiny meatballs (like little balls of ground up meat), tiny pasta (like little noodles that are shaped like stars), and spinach (like the green leaves we sometimes put in salad).
All of these things are mixed together in a big pot with some chicken broth (like soup made from cooking chicken in water) and then cooked until it's really hot and all the flavors have mixed together.
It's really tasty and warm and comforting, and people like to eat it when they're celebrating something special like getting married.
