Brown chicken pieces in 4 tablespoons of butter and set aside.
Brown chicken flaored Rice a Roni in 2 tablespoons of butter. Remove to 3 quart casserole. Stir in hot water, contents of "special seasonings" pack, stewed tomatoes and salt.
Arrange chicken pieces on top of casserole, cover and bake at 375 degrees for 35-40 minutes. Then cook uncovered 10 minutes. Test chicken for doneness -- it might need a few more minutes depending on size.
NOTE: To give this dish some extra heat, use Rotel tomatoes with chiles instead of stewed tomatoes.
