I found it in a book called Once-A- Month Cooking; the idea is that you do all or part of the preparation ahead, and thaw and heat or finish the results. I'm going out tonight, so I made this last night for my family - that's the only reason I remember the ingredients!
Mix together everything except chicken breasts. Pour into an 11x7" pan. Sprinkle the chicken breasts with salt, pepper and paprika, place on top of rice. (At this point it can be frozen until wanted).
To prepare: thaw, and bake at 375 for 1 1/4 hours.
