Instructions

1. 1
   Preheat the oven to 400 degrees F (200 degrees C)
2. 2
   Set a large deep cast iron skillet over medium-high heat. Add olive oil and swirl to coat skillet evenly. Add onions to skillet in one even layer; top with ground beef, breaking it up into small pieces. Cook undisturbed until onions are translucent, about 2 minutes. Stir beef and onions until well combined, and cook until beef is cooked through and browned, stirring occasionally, 3 to 4 minutes longer.
3. 3
   Reduce heat to medium. Season beef with garlic powder, onion powder, and black pepper. Cook, stirring often, for 1 more minute. Remove from heat. Add cream of mushroom soup, green beans, and corn; stir until well combined.
4. 4
   Toss tater tots and seasoned salt in a bowl to combine. Arrange tater tots decoratively over beef mixture in the skillet, avoiding large gaps between tots.
5. 5
   Bake in the preheated oven until tater tots are golden and crisp, about 1 hour. Sprinkle with cheese and scallions; cool 10 minutes before serving.
