Peel/ scrape the carrots and slice them into 1/2" thick roundels.
If your carrot is thick/ fat, cut the carrot lengthwise and then slice into 1/2 " pieces.
Steam cook, microwave or boil in lightly salted ware till just done.
Dice the onion into slightly big pieces (I cut each onion half into 4). Dice the bell peppers into a similar size. Keep aside.
Heat the oil, add the onion and sautxe9 on high heat for a couple of minutes till it turns pink. Add the bell pepper and sautxe9 till soft. Now add the cooked carrot, salt and pepper and stir for a couple of minutes.
In a small bowl whisk together the cornstarch, red chilli sauce, tomato ketchup, vinegar, sugar and about 1/4 a cup of water, till smooth. Pour this into the vegetables, stirring throughout, and allow to cook (on medium heat) for about 3 to 5 minutes till it thickens a bit. If you feel the mixture is too thick, add a little more water and cook for another minute.
Pour into a serving dish and garnish with chopped spring onion greens.
Serve with noodles or fried rice.
