Heat oven to 425 degrees. In a large bowl, combine the pork, ssamjang, panko, scallions, ginger, garlic and ½ teaspoon salt and use your hands to gently mix.
Shape the meat into 16 balls (about 1 ½ inches in diameter) and arrange on a parchment or foil-lined, rimmed baking sheet.
Bake until golden and cooked through, about 15 minutes. Serve warm, sprinkled with scallions, in lettuce cups with rice if desired.
