This chicken pot pie uses mashed tater tots for its bottom crust. It also uses commercially made pie crust for the top, and rotisserie chicken (hopefully your grocery store offers roasted chickens for sale). All of these shortcuts are what constitute the PMS part (pre-made stuff), but the rest is made from scratch, which is only way to guarantee melt-in-your mouth goodness.
It really gets the job done when you need some hardcore comfort food, in which case the other meaning of PMS might apply. ;-)
