In a large pot, heat the stove to medium, then add the lean ground beef. Cook for 5-7 minutes until browned and crumbles easily. Drain excess fat and transfer beef to a bowl.

While the beef is browning, prepare the macaroni according to package instructions in a separate pot for about 7-9 minutes. Once done, drain and set aside.

Lower the heat on the pot and return the beef, macaroni, and mixed vegetables back into the large pot. Stir gently to distribute the ingredients and cook for an additional 3-5 minutes.

Add salt, pepper, and garlic powder, mixing well. Cook for 2 more minutes until aromatic and well combined.

Serve hot in bowls or plates and enjoy the warm, nostalgic flavors with your family or loved ones.
