Heat canola oil in a cast-iron or nonstick skillet. Once hot, shake off the excess marinade and place the pork on the pan. Sear for a minute, then turn the pork over and sear the other side for another minute. Lower the heat to medium-low and lightly brush with the reserved marinade. Continue cooking for 6-8 minutes, turning frequently, until the pork is charred on the outside and cooked to your liking. Transfer to a plate and allow to rest for 5 minutes. Then slice and serve.
