Brown the ground beef, onion and bell pepper in a skillet over medium heat. Drain any excess fat and return pan to stovetop.
Add in the tomato sauce, noodles, tomato paste, garlic salt, beef broth and Marinara Sauce Mix and stir to combine. Bring mixture to a boil, and then reduce heat to a simmer. Cover and cook until pasta is tender (about 15 minutes).
Stir mixture then top with shredded mozzarella cheese and cover again to let cheese melt. Once melted, serve and enjoy!
