Cook the pasta according to the package directions, then drain and set aside.
In a large pan, brown the ground beef thoroughly over medium heat. Once browned, drain any excess fat.
Sprinkle the taco seasoning over the cooked beef and pour in the water. Stir well and allow it to simmer until the liquid has evaporated.
Return the cooked pasta to the pan, then add the salsa and shredded cheddar cheese.
Stir everything together until the cheese is fully melted and the ingredients are evenly combined.
Serve immediately, and for an extra crunch, top with tortilla chips if desired.
