Slice your pork tenderloin into thin medallions - approximately 1/2 inch thick. Your tenderloin will be easier to slice if it is slightly frozen.
2 pork tenderloins,
Place your pork medallions into a bowl and toss with salt, Montreal steak spice, oregano and pepper. Next add the oil and mix well with your hands to coat all of the pieces evenly.
1 tbsp salt, 1½ tsp Montreal steak spice, 1 tsp dry oregano, ½ tsp pepper, 1½ cup vegetable oil
Allow to marinate in the refrigerator for at least 30 minutes. You can also marinate your meat for longer if you prefer (up to a day).
Place a large colander over a bowl and drain your pork while reserving the marinade. Allow to drain for 15 minutes at room temperature. Discard the marinade.
Using a meat tenderizer or mallet flatten your pork medallions until they are about 1/4 inch thick.
Add enough vegetable oil in a large skillet to cover the base of the pan (about 2-3 tablespoons). Heat the oil and fry the pork medallions in batches being careful not to overcrowd the pan. Fry for about 2 minutes per side, internal temperature should be 145℉.
