Crock pot pork tenderloin marsala

I started off by removing the silver skin on the pork tenderloin. Just use a sharp knife and cut right under it to remove it from the tenderloin. It really isn’t edible so make sure to do this. Then I seasoned the tenderloin with salt and pepper. Next I browned them quickly in a saute pan in a little oil. I removed them to put them in my crock pot. I used my 9 x 13 crock pot which I have really come to love. Then I browned the onions and added them on top of the tenderloins. Then I sauteed some mushrooms and added them also. I deglazed the pan with the Sweet Marsala and added it to the pan
