Brown the ground beef in a large skillet over medium-high heat. Drain off any excess grease.

Add the chopped onion and minced garlic to the skillet and cook until softened, about 5 minutes.

Stir in the diced tomatoes, beef broth, Italian seasoning, salt, and pepper. Bring to a simmer.

Add the egg noodles to the skillet and cook until tender, about 8-10 minutes, or according to package directions.

Serve immediately.
