1. Preheat the oven to 200ºC fan-forced.
2. Place the sweet potato, spring onion and garlic into a baking dish (evenly spread across the dish).
3. Pour over the eggs and then top with the asparagus spears. Push the asparagus down slightly so it is lightly covered by the egg.
4. Bake in the oven for 25-30 minutes until cooked through.
5. Cut into 6 squares and store in the fridge.
