Mix the rice (I rely on plain old Uncle Ben's Converted Rice for things like this) and soups in a casserole that has a tight-fitting lid.
Put the butter or margarine in the middle - don't stir.
Cover and bake for 45 minutes at 350 degrees. Before you serve it, fluff it with a fork, stir it if you must.
Okay -- you can make some changes. I think reducing the butter to 1/4 stick doesn't hurt. To turn this into dinner, season and brown a few pork chops in a skillet, and place the chops on top of the rice/soup/butter before you put the casserole (or foil-topped baking pan) into the oven.
