I found a pork tenderloin recipe on line by Ina Garten.  I just used it for timing and oven temperature.  I usually grille my tenderloins outside, but Jim did not want to grille in 9” of snow.  Having been in the hospital, I had to look in the refrigerator to see what I could find to marinate the tenderloin in.  I found many herbs, rosemary, thyme, and others and put them in a bag with a product I had bought somewhere that had a marinade type of name.  Used that also.  

Ingredients:

See above.  

Directions:

1. Warm oven to 450 degrees F.  Roast for 20-25 minutes.  I used 20 minutes and cover with aluminum foil for 10 minutes.   It was a perfect 140 degrees F.  That is my pork temperature.  
2. I roasted the potatoes for 45 minutes, so started oven early to accommodate the difference in timing.
