Beef, Rice and Corn Supreme

Not sure what else to call it than what it really is. White Rice, Ground Beef and Corn. This is another dish that I really don't remember putting in it, but Quinn thought it was delicious and believe or not, so did Mckayla.

1/2 pound of Ground Beef
small onion, chopped
small can of Cream and Mushroom Soup
Salt and Pepper
