Ingredients:

Button Mushrooms -  250 grams 

Onion - 1(Chopped finely)

Ginger - 1/2 inch piece(chopped finely) 

Garlic - 2 cloves 

Chilli Powder - 1/2 tsp 

Turmeric powder - 1/4 tsp 

Garam Masala - 1/4 tsp 

Pepper Powder - 1/4 tsp 

Salt - as required 

Oil - 2 tsp

1. Immerse the button mushrooms in warm water for 5 minutes. Then clean it with a damp cloth to remove the dirt and chop each mushroom into 3-4 pieces lengthwise. Chop the ginger, garlic and onions finely. Heat a pan and add the oil. Then saute the chopped ginger and garlic pieces until nice aroma comes.
2. Then add the curry leaves and chopped onion. Once the onions turn transparent, add the chilli powder, turmeric powder and garam masala. Saute it until the raw smell of the masala leaves. Finally, add the chopped mushrooms. 
3. Mix it all together, so that the masala coats the mushrooms. Turn the flame to low and cover cook the mushrooms until it is soft and tender. Mushroom leaves enough water and hence it is not required to add water. Add required salt at this stage. When the mushroom turns tender and the water content is dried up completely, sprinkle the pepper powder and give everything a gentle mix. Garnish it with the chopped coriander leaves and switch off the flame.
