In a cooking pot, heat oil and add onions and cook until they turn golden brown.
Add cumin and sauté until aromatic.
Add ginger and garlic paste and sauté until aromatic.
Add tomatoes and yogurt. Mix well, cover and cook on low for 5-6 minutes until tomatoes are soft.
Add salt and biryani masala. Stir for a minute.
Add carrots and potatoes and stir fry until 50% done.
Now add peas, corn and green beans and cook for 5 minutes. I used frozen but if you are using fresh vegetables then put them with carrots and potatoes.
Lastly add water and drained rice and dried prunes.
Allow the water to be absorbed by rice on medium flame.
When all the water evaporates, put on dum for 10-12 minutes.
Lastly add freshly chopped coriander and green chilies.
