Get your oven hot at 375°F (190°C) and grease a 9x13 inch dish before you start anything else.

Grab a big bowl and lightly mix your beef, pork, diced onion, breadcrumbs, milk, egg, Worcestershire sauce, salt, pepper, and garlic powder. Don't go overboard with mixing.

Push the meat mix into your greased dish, making sure it's flat and even all around.

Cover the meat with an even layer of mashed potatoes, then scatter cheddar, bacon bits, and green onions on top.

Stick it in the oven for about 35-40 minutes until the cheese gets all bubbly and the meat cooks through. Let it sit for 10 minutes before you cut into it.
