In a kadai, heat oil and add cumin and fennel seeds. Once it sizzles, add onions and saute till they turn golden.
Then add ginger-garlic paste and fry for 2-3 minutes or until raw smell goes.
Add the tomato puree and fry for 2 minutes. Then add turmeric powder, red chilly powder, coriander powder, crushed black pepper and fry for a minute.
Cover and cook for 5- minutes or till the tomatoes and spices have cooked well.
Add the mushrooms and saute for 2 minutes. Then add the green peas, powdered cashews, ½ cup water, salt and mix well.
Cover and cook in medium heat until the mushrooms have cooked, about 4-5 minutes. Mushrooms will leave water, so there is no need to add more water.
Once the mushrooms have cooked, add garam masala and coriander leaves. Remove from heat
