Mix half a block of tofu, 3 tablespoons of cold cooked rice, 1 tablespoon of chopped green onion, and 2 eggs.
Add 100ml water, a pinch of salt, 1 tablespoon mirin, and 1 tablespoon anchovy fish sauce to the egg mixture and mix well.
Cover with plastic wrap, poke holes with a fork, and microwave for 5 minutes in a microwave-safe container.
Remove the plastic wrap, drizzle 1 tablespoon of sesame oil, and sprinkle sesame seeds to taste. Done!
