Cook the pasta in accordance with the package instructions then drain and leave in the strainer.
While the pasta is out of the pot, place the block of cream cheese and milk in it and let it melt, stirring it occasionally so that it does not burn. The heat can also be lowered a bit.
Pour the pasta back into the pot once the cream cheese is melted, then stir it up to mix with the pasta.
Add in the garlic salt to taste and the chicken.
Mix well and serve topped with parsley and cheese.
