Blend the creamy tofu sauce: add the silken tofu, peanut butter, soy sauce, sesame oil, and garlic to a blender. Blend until completely smooth, then set aside.
Cook the spicy pork: heat chili oil in a pan with minced garlic and green onion until fragrant. Add the ground pork and cook until browned and cooked through.
Season the pork: stir in the gochujang, soy sauce, and honey. Cook until everything is evenly coated and well seasoned.
Assemble and serve: place the udon in a bowl or plate, add the spicy pork, pour the creamy tofu sauce over the noodles, and finish with extra green onion and chili oil if desired.
