Add the mirin and cook for about 5 minutes until reduced slightly. Add the soy sauce and cook for about 2-3 minutes. Add the spinach and cook until slightly wilted.
Gently add the glass noodles and blend with the pork mixture. Top with dry roasted peanuts and sliced green scallions and serve immediately.
