Spicy pork belly stir-fry with cheese

Slice the pork belly into thin, bite-sized pieces, approximately 0.5 cm thick and 5 cm long.

In a large mixing bowl, combine the gochujang, gochugaru, soy sauce, minced garlic, minced ginger, mirin, sesame oil, sugar, and black pepper to create the marinade.

Add the sliced pork belly to the marinade, ensuring each piece is thoroughly coated. Marinate for at least 30 minutes at room temperature, or up to 2 hours in the refrigerator for deeper flavor.
