Everyday kitchen measurements
For 3 servings. Use a small 180 ml paper cup, a level eating spoon (about 15 ml) and a small teaspoon (about 5 ml).
How to fill the cup and spoons
Use the same cup and spoons throughout. Their sizes vary, so these amounts are approximate. Spoon flour in loosely and level the top without pressing. Measure vegetables after chopping, without packing them down. The amounts in g/ml are the original reference quantities. For part of a pack, use the specified pack weight and divide the contents evenly.

Step-by-step cooking
-
Step 1

Check the sausage packet says fully cooked and follow its reheating instructions. Cut the sausages lengthwise into quarters, then into short pieces, especially for children. Chop the onion and bell pepper into small bite-size pieces.
-
Step 2

Mix ketchup, soy sauce, 1 eating spoon of water and the optional sugar in a small bowl. Keep it beside the stove so the sausages do not burn while you prepare the sauce.
-
Step 3

Warm the oil in a pan over medium heat. Add onion and stir for 2 minutes, then add bell pepper and cook for 2 minutes more. If using carrot instead, cook until just tender before the next step.
-
Step 4

Add the sausage pieces and stir-fry for 3–4 minutes until lightly coloured and hot throughout. Follow a longer packet reheating time if required. Reduce the heat if the vegetables begin to scorch.
-
Step 5

Turn the heat to low, pour in the ketchup mixture and stir for 1–2 minutes until everything is coated and the sauce bubbles. The sausages must be steaming hot throughout, not merely warm on the outside.
-
Step 6

Turn off the heat and serve small portions beside rice. Let children’s portions cool to a safe eating temperature and cut any large pieces smaller. Refrigerate the remainder promptly using a clean container.
Finished dish

Use fully cooked sausages, not raw sausages. For young children, avoid round sausage coins or whole cocktail sausages: cut lengthwise into narrow pieces and then smaller bites. This is a salty occasional side dish; the optional sugar can be left out. Refrigerate leftovers in shallow containers within 2 hours, or within 1 hour above 32°C. Keep at 4°C or below, use within 3–4 days and reheat cooked leftovers to 74°C.
