Heat a large skillet over medium heat and add the ground beef and chopped onion. Cook, breaking up the meat as you go, until the beef is completely browned and the onion is soft and translucent, about 6-8 minutes. Drain off any excess fat.

Stir the diced tomatoes (with their juice), cream of mushroom soup, garlic powder, Italian seasoning, salt, and pepper into the beef mixture. Let everything simmer together for a couple minutes so the flavors can meld.
