I have been looking for this yummy, very filling recipe and finally found it on a People magazine website. I think it tastes exactly like Panera, especially when reheated. Don't forget to add milk when reheating.
I am writing this recipe as published, adding my little notes.
12/13/11 - I am changing the hot sauce to optional...The second time I made this, my DH put a little more than the 1/4 tsp (probably 1 extra drop) and all you could taste was hot sauce. I started making it without the hot sauce and it's fine.
