Add the pork slices, pear or apple, garlic, soy sauce, chili paste, ginger, brown sugar, sesame oil, and rice vinegar to a large zip top baggie. Seal and shake to combine.
Let sit at room temperature for up to an hour or marinate in the refrigerator for up to eight hours.
When ready to cook add a tablespoon of vegetable oil to a pan and add in the pork and half of the marinade.
Saute for 3-5 minutes or until the pork is cooked through.
Season with salt and pepper.
To serve place a spoonful of rice on a Bibb lettuce leaf along with a scoop of the pork and sauce. Sprinkle with scallions and enjoy!
