Clean well the Button Mushrooms & allow it to dry out a bit by dabbing it with a kitchen towel and then, very carefully break it's stems from the pods without causing any damage to the mushrooms

Collect all the stems in a bowl & now scour the inside of the mushrooms holding the same very gently & carefully, with a spoon & again collect all the residues in another bowl & don’t throw it away since it’s all edible

Now, chop finely the mushrooms stems in thin slices, along with the residues that was scoured in from the button part of the mushrooms & keep them all aside

Heat a frying pan with the measured oil and pour in the onion slices, sauté until translucent & then put in the 3G paste & keep sautéing for about a minute & then, add into it the aforementioned veggies and keep sautéing

Add in the salt and sugar & give it a nice mix and now, & cover & cook in low-medium heat for 5 mins...once well sautéd, now add in the finely chopped residuals of the mushrooms that are all previously collected in a bowl

Keep sautéing for another a couple of mins. Now, goes in the red chilli powder, red & green chilli sauces & the butter & also the dark soy sauce & give all a nice mix until all well incorporated

Finally, when the oil leaves the pan & the stuffing is well cooked with a nice spicy smell all around, add in the black peppercorns & a bit of grated cheese aforementioned (half of it) & turn off the flame

Now, allow the stuffing to cool down a bit to get well stuffed into the already scoured mushrooms & then, stuff it well

In another frying pan take a tbsp of butter keeping the flame in low & then place the stuffed mushrooms carefully & sprinkle the rest of the grated cheese on the top & allow it to cook for just not more than 2 mins each sides by covering the pan

Alternatively, this last step can also be done in the microwave by preheating the same for 10 mins @180C & then place the stuffed mushrooms on a baking tray- well greased with the butter and bake in the convection mode for about 3-5 mins. (Varies with different microwave temperature settings)

Take it out & sprinkle & garnish with the grated cheese on it's top before serving it onto the plates
