Chinese Buffet Imitation Crab Casserole

I found this recipe and many others googling but this one sounded very much like what I was looking for except it did not include celery.  I added an equal amt of celery and onions and pretty much followed the recipe as it is listed on Please Give Peas A Chance blogspot.  I really liked it and the next day we warmed what was left and made what I called "Poor Man's Crab Roll".
