Let’s dive into the process of bringing this comforting meal to life:

1. In a large bowl, combine ground beef, breadcrumbs, egg, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix until well combined.
2. Shape the mixture into small meatballs, about 1-inch in diameter.
3. Heat olive oil in a large skillet over medium heat. Add the meatballs and brown them on all sides. Once browned, remove them from the skillet and set aside.
4. In the same skillet, add the chopped onion and sauté until translucent, about 5 minutes.
5. Stir in the flour and cook for 1-2 minutes. Slowly whisk in the beef broth, ensuring there are no lumps.
6. Add tomato paste, soy sauce, and butter to the skillet. Stir until well combined and bring to a gentle simmer.
7. Return the meatballs to the skillet, cover, and let them simmer in the gravy for 15-20 minutes, or until cooked through.
8. Meanwhile, in a large pot, boil the potatoes until tender, about 15 minutes. Drain and return to the pot.
9. Add milk and butter to the potatoes, mashing until smooth and creamy. Season with salt and pepper to taste.
10. Serve the meatballs with a generous helping of mashed potatoes, drizzling extra gravy on top.
