Chop the tomatoes, cilantro, green onions, and avocado slices.
Cook the ground beef. I season my ground beef with garlic powder and salt because my kids prefer it that way. You can use Mexican seasoning if you like it more spicy.
On a baking sheet covered in parchment paper, arrange the tater tots in a single layer that covers the sheet.
Sprinkle half of the shredded cheese over the tater tots. Next, sprinkle ground beef, corn, beans, and the rest of the shredded cheese on top.
Bake at 400ºF for 30 minutes.
Garnish with sour cream and fresh toppings like avocado, cilantro, and green onions.
