Whisk in an egg with some salt & black peppers until frothy & mix it well alongwith the mushrooms to get properly coated with

Now, in the same pan & oil: Over the medium heat- Add in the sliced onions with some salt & green chillies and sauté until translucent & releases nice aroma

At this point: Add in the Bell peppers, chopped garlic & ginger & sauté again for a minute or so- until the veggies are well cooked

Now, add in the dark soy sauce, freshly crushed black peppers, chilli sauce & rest all other ingredients aforementioned except the cornflour slurry

Mix everything well together until nicely combined- Add in the spring onions (greens), add in some water & give it a really good mix to be well incorporated

Reduce the flame to low-medium & cover the lid of the pan & cook it for another 5-6 mins time, stirring occasionally in between

Once done: Open the lid- Add in the cornflour-water slurry & mix nicely...Also, add in a tsp of White/Apple Cider Vinegar to it & give it a final good mix- everything, altogether & turn off the flame

Allow it to sit on the oven for about 10 mins time, on the standby position before serserving piping hot with the hot noodles, fried rice or similar
