In a large skillet or Dutch oven, brown the ground beef over medium-high heat.
Drain excess fat, then add diced onion and bell pepper. Sauté until tender, about 5 minutes.
Pour in beef broth, diced tomatoes, and tomato sauce. Stir to combine.
Season with salt, chili powder, garlic salt, and Italian seasoning. Stir well.
Bring to a boil, then add elbow macaroni. Stir to combine.
Reduce heat to medium, cover, and simmer for 15-20 minutes until the macaroni is tender.
Remove from heat and garnish with shredded cheddar cheese, if desired.
Serve hot and enjoy!
