You need a tawa. I used my iron tawa which I use for rotis and parathas. Heat the tawa with oil, crackle jeera, then add ginger garlic paste along with onions. Fry for 2mins.
When onion gets fried, puree a tomato in a mixer and add it.
Mix well then add red chilli, coriander, jeera and garam masala powder and cook till raw smell of tomatoes go.
Add required salt. Keep cooking till becomes thick.
Then add mushrooms. Cook for around 3-5mins till mushrooms absorb the masalas and get cooked fully but should retain its crunch.
Finally add capsicum, toss around and cook for 2mins.
Add 1 teaspoon of oil if it sticks to the tawa. Add freshly cracked pepper, kasoori methi and chopped coriander leaves, give a quick mix and switch off.
Serve Tawa Mushroom with rotis / parathas / veg pulao.
