This is the pork tenderloin that we always serve at demos at Altomonte's
Preheat oven to 400 degrees F (use convection if you have it)
Rub pork tenderloin with olive oil, then completely cover with Philly Grit
Place tenderloin in a pan on medium high heat. Sear pork on all sides until browned - about 2 minutes per side.
When all sides of the pork are browned, put the pork tenderloin into the preheated oven. If the pan is oven-safe, you can put the entire pan in. Otherwise transfer to a baking sheet or roasting pan.
Cook in oven until the internal temperature reaches 145 degrees F. Remove from oven and allow pork to rest for 3 minutes before slicing.
