Creating this amazing Hobo Casserole is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Cook Ground Beef: In a large skillet over medium heat, add olive oil. Once hot, cook the ground beef until browned. Drain excess fat.
3. Sauté Vegetables: Add chopped onion to the skillet, and sauté for about 3-4 minutes until softened.
4. Mix Ingredients: Stir in frozen mixed vegetables, cream of mushroom soup, milk, salt, pepper, garlic powder, and onion powder. Mix well.
5. Prepare Baking Dish: In a greased 9×13-inch baking dish, layer half of the sliced potatoes evenly at the bottom.
