Cut the seaweed and pork into bite-sized pieces.
Slice the onion and bell pepper thinly.
Heat cooking oil in a pan and stir-fry the pork.
Add the onion and bell pepper, and stir-fry together.
Add the seaweed and stir-fry a bit more, then season with ramen soup powder or soy sauce.
Transfer the stir-fried ingredients to an oven-safe dish and generously top with mozzarella cheese.
Bake in a 200°C (392°F) oven for 10 minutes.
When the cheese is golden brown, it's ready to serve.
