Basically, you sweat the celery for a little while, add chicken stock and set to simmer. When the celery is breaking down and the stock has reduced a bit, you add some stirfry noodles, and cook until ready. I couldn't find any stirfry noodles in the cupboard, so I added some bowtie pasta a little earlier.
It was good. I just wish I could take photos as well as Pepper.
