the gochujang, pineapple juice, honey, sesame oil
, ginger and garlic together in a medium bowl.
Place the pork in a zip-top bag and pour the gochujang mixture over it. Seal the bag and shake well, making sure that the marinade
coats the meat. Refrigerate for at least 6 hours or overnight.
Heat a grill pan
on medium-high heat or prepare an outdoor grill. Cook the pork
until grill marks appear, about 3 minutes per side. Remove to a board and cut into bite-size pieces.
On a serving platter, make separate piles of chiles, lettuce leaves and Korean Bean Sprout Salad. To make a lettuce cup, spoon some rice in the center of a lettuce leaf, top with a few pieces of pork, some chiles and salad, sprinkle with sesame seeds and fold.
