Bring a pot of salted water to a boil and cook the pasta according to package instructions until al dente.

In a large skillet, brown the ground beef or turkey over medium heat until fully cooked.

Add the taco seasoning and diced tomatoes to the meat, stirring to combine.

Reduce the heat and mix in the cream cheese until melted and creamy.

Stir in the cooked pasta, shredded cheddar cheese, and milk until well combined.

Cook over low heat until the cheese is melted and the mixture is heated through.
