Add chopped tomatoes, cook for 3 minutes.
Add the cooked beef along with the gravy.
Add coriander powder, garam masala & salt if required.
Combine well and cook for 10 to 15 minutes till the liquid dries off.
At this point, increase the heat to high and stir fry till onions & beef turn light brown.
Add chopped cilantro, mint leaves and lemon juice; stir fry at high heat for a minute.
Finally, add vinegar and stir fry for a minute.
Remove the saucepan from the heat and keep covered for 15 minutes.
Serve into a bowl and enjoy with rice, chapati, poori, naan or roti.
My favorite combination is beef roast & poori- YUM!
