Preheat oven to 325 degrees Fahrenheit.

Mix ground beef with dry oats. Mix in 1-2 tbsp of tomato soup. Add pepper and garlic powder (and salt if wanted).

Press into backing dish (smaller and deeper works better).

Spoon in the rest of the tomato soup. Ensure top of meatloaf is fully covered.

Bake uncovered at 325 degrees Fahrenheit for 1-1.5 hours.

Slice into the middle to ensure hamburger is fully cooked.
