I've been making this recipe since it was first published in 2003. I use a store-bought rotissiere chicken and I defrost the frozen hash browns overnight in the fridge or in the microwave. I double the amount of bbq sauce (we use Sweet Baby Ray's).
This dish was fairly quick and easy to prepare and cook. The whole family really liked this dish, even my 3 year old. I didn't have celery so I left it out. I would definitely make this again.
I did not care for this dish. Rather than my hash being soaked as other commenters have noted, my hash did not have enough sauce (perhaps I over compensated after reading all of the reviews). The veggies did not seem to blend well together, and although I used our favorite bbq sauce, the taste was very odd. I would not make this dish again.
