Cook and crumble the ground beef in a large skillet, over medium-high heat, until no longer pink. Drain any grease. Add salt, pepper, taco seasoning and water to beef. Continue to stir and bring mixture to a boil. Turn off heat and carefully pour beef into a greased 7-quart slow cooker.
Add the crushed tomatoes, salsa, broth, corn and nacho cheese dip. Stir. Cover with lid and cook on Low heat for 5 to 6 hours OR cook on High heat for 3 to 4 hours.
Add small pasta shells to slow cooker. Stir, then cover with lid. Cook another 20 minutes on High heat or until pasta is cooked and tender. Sprinkle the cheese evenly over the top.
Serve taco pasta in individual bowls and top with your favorite taco toppings. Enjoy! :)
