Marinate the beef mince in soy sauce, sesame oil and sugar. Cook in a pan over high heat until browned. Set aside.
Prepare each topping separately: blanch and season the spinach; stir-fry the carrot, mushrooms and courgette separately with a little oil and salt; blanch and season the bean sprouts.
Make the gochujang sauce: mix all sauce ingredients together.
Fry the eggs sunny-side up.
Divide the hot rice between 4 bowls. Arrange each topping in separate sections over the rice, like a clock face.
Place a fried egg in the centre. Drizzle sesame oil over the bowl. Scatter sesame seeds and nori strips on top.
Serve with the gochujang sauce on the side. Mix everything together vigorously before eating.
