Line tater tots side by side in one layer that covers the bottom of a flat casserole dish.
Thoroughly brown ground meat (salt & pepper to personal taste if desired) in a skillet. If you’ve chosen to include the drained can of corn, do so after the meat has browned & continue to cook for another couple of minutes.
Layer the browned meat over the tots until they are completely covered.
Layer the Cream of Mushroom soup over the meat until it’s completely covered.
Layer the shredded cheese over the soup until completely covered. If desired, you can decorate the top of the cheese with patterns made out of spare tots.
Bake for 25 minutes or until cheese is golden brown.
