Prepare the pork tenderloin by patting dry with a paper towel
Combine the ingredients for the spice rub and sprinkle on all sides of the pork tenderloins, patting the spices in with your hand.
Heat an oven safe skillet or cast iron pan over medium high heat. Pour in the olive oil and brown the pork tenderloins for 2-3 minutes on each side. Add the garlic and cook and stir for 30 seconds until fragrant.
Mix together the ingredients for the balsamic glaze and pour over the pork tenderloins.
Transfer the pan to the oven and cook for 20-25 minutes until the internal temperature reaches 145ºF, check using an instant read thermometer
Allow to rest 3-5 minutes before slicing. Spoon the balsamic glaze over the top of the sliced pork tenderloin.
If you do not want the tenderloins to be pink in the center, you can cook them to an internal temperature of 165ºF
