Thinly slice the onion to reduce greasiness. If you like spicy flavors, prepare chopped chili peppers as well.

Cut the leftover jeon into bite-sized pieces.

In a microwave-safe dish, mix the jeon, onion, and spaghetti sauce according to your taste.

Top with a generous amount of pizza cheese and sprinkle parsley powder over it.

Microwave until the cheese melts completely.
