Heat your oven to 425°F. Warm some butter or margarine in a large frying pan. Drop in the ground meat and cook until browned, breaking it into chunks as it cooks. Toss in the chopped onions and sauté until they soften and the meat's fully done.

Add the whole can of corn (don't drain it), pour in the water, and sprinkle in the gravy mix. Toss in the salt, garlic, pepper, and onion powder. Stir really well and let it all simmer together for a couple of minutes.

Boil 1 1/2 cups of water with the butter in a pot. Once it starts bubbling, take it off the heat and mix in the potato flakes and milk. Let it rest for about a minute, then stir until it's silky smooth.

Grease up a 9x13 dish and spread the cooked meat mixture over the bottom. Scoop the mashed potatoes over that and smooth them out. Top everything with an even layer of frozen tater tots.

Slide the dish into the oven and bake for half an hour. Pull it out, scatter the shredded cheese on top, and bake for another 5 minutes or so, just until the cheese melts and starts getting golden.
