Preheat the oven to 375F/ 190C.
Place all the ingredients apart from the egg, in a microwaveable bowl. Stir gently to mix together. Microwave for 1 minute.
Stir and microwave for another 30 seconds or until fully melted. Mix until all is combined.
Add the egg then mix fast until smooth and fully incorporated to make a cheesy dough.
Place on a parchment-prepared baking tray and form into a circle shape.
Bake for 15 minutes. Take out and spread 1/3 cup of tomato sauce, mozzarella cheese, kimchi, and green onions. Then, place back in the oven for another 7 minutes or until cheese is golden brown. Add some fresh chopped green onions and slice. Enjoy!
