Put your noodles on to cook first and then in a frying pan over medium heat, add the 2 tbs of vegetable oil - when the oil is glistening (1-2 minutes), add the minced garlic and thyme and stir until fragrant (about a minute). Add the chicken breast bits and salt and pepper with a pinch of each. Stir frequently until cooked through. When cooked through, set aside.
While the chicken is cooking and the noodles are starting to boil, in a medium saucepan on medium heat, heat the cream cheese, butter, parmesan cheese and milk until melted and starting to bubble. Stir continuously so as not to burn. Once it starts to bubble, remove from the heat and add the chicken to the sauce. Stir well.
When ready to eat, plate the noodles and pour the sauce over each portion.
