I think eating leftovers ought to be part of the wedding vows!
If your soup noodles and veggies are a little on the overcooked side or would become so with further cooking, just remove them and (sadly) discard them or use the veggies in a pot pie or mix them in with the dog's food. You could freeze the soup and bring it out a month or so later and let everyone think you made it from scratch again. I would offer your leftover pea soup to a neighbor (wish we were neighbors). All the other suggestions are things I've done and they turn out really good. You could always forget the leftovers for today and just make breakfast for dinner. Love that.
