Steps
1. Boil the diced potatoes in salted water for 5-7 minutes until just tender, then drain.
2. Heat vegetable oil in a pan over medium heat. Add carrot slices and sauté for 3 minutes.
3. Add the boiled potatoes to the pan and stir-fry for another 3 minutes.
4. Lower heat and add butter and curry powder, stirring to coat the vegetables evenly. Cook for 2 minutes until fragrant.
5. Push vegetables to the side of the pan. Crack the egg into the empty side and scramble gently until cooked through.
6. Mix the scrambled egg with the vegetables, add soy sauce and salt, and stir well.
7. Garnish with chopped green onion if available. Serve hot.
