Heat oil in large pan on medium high heat. Once oil is hot, add freshly grated ginger/ginger paste and garlic paste and saute for 1 minute till the flavor comes out.
Garnish with fresh coriander and the remaining sliced ginger. Serve with naan/chapati or fresh steamed basmati rice.
A quick way to make fresh ginger paste is to use a grater. Just cut off a piece of ginger, and grate it on the sides of a small grater.
