In a small bowl, whisk together the gochujang, tamari, toasted sesame oil, honey, rice vinegar, minced garlic, and grated ginger to create the marinade.
Cut the pork tenderloin into 1-inch cubes and place them in a bowl, tossing with the marinade until every piece is thoroughly coated.
Let the pork marinate for at least 15 minutes to allow the flavors to penetrate the meat.
While the pork marinates, chop the red bell pepper into 1-inch squares and slice the green onions.
Thread the marinated pork cubes and red bell pepper chunks alternately onto wooden or metal skewers.
Heat a grill or grill pan over medium-high heat and lightly grease with a touch of oil.
Grill the skewers for 8 to 10 minutes, turning every few minutes, until the pork is cooked through and the edges are beautifully charred.
Steam the shelled edamame in a small amount of water for 3 minutes, then drain and season with sea salt and black pepper.
Serve the skewers over the warm edamame and garnish with sliced green onions and sesame seeds.
