To create an amazing Hobo Casserole that everyone in your family will enjoy, just follow these simple steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C).
2. Brown the Beef: In a large skillet, brown the ground beef over medium heat. Stir occasionally until fully cooked, about 5-7 minutes.
3. Sauté Onions: Add diced onions to the skillet and cook until they become translucent, around 3-4 minutes.
4. Mix Vegetables: Stir in your choice of mixed vegetables, cooking until they’re heated through. If using frozen vegetables, ensure they’re thawed first.
5. Add Tomato Sauce: Pour in the can of tomato sauce. Season with salt, pepper, and optional Italian seasoning for extra flavor. Mix everything well.
6. Transfer to Baking Dish: Pour the beef and vegetable mixture into a greased 9×13-inch baking dish, spreading it evenly.
7. Add Cheese: Sprinkle shredded cheese generously on top, covering the entire mixture.
8. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes. The cheese should be bubbly and slightly golden.
9. Serve: Allow to cool for a few minutes before serving to avoid burns from hot cheese.

This method ensures you have a delicious, bubbling hobo casserole ready to please a crowd!
