Preheat oven to 350F.
Saute green onion, garlic, green pepper, and carrot in vegetable oil over medium heat for a couple minutes.
Combine beaten eggs with milk, salt, black pepper, garlic powder, and onion powder in a medium bowl.
Mix bread crumbs and flour into ground chuck and ground pork with your hands.
Press the mixture into a meat loaf pan (the kind of pan with drainage holes on the bottom) or a large loaf pan.
Bake for 30 minutes, then spread 1/4 cup of letchup over the top of the meatloaf and bake for another hour.
Remove from oven and allow it to sit for 10 minutes before slicing and serving.
