First wash spinach well and keep aside. Now heat 1 tbsp oil in a pan and add ginger, green chilli and onion. Saute for 2 min. Now add spinach to it and again saute for 2 min. Let it cool for 5 min.
After cooling blend it without water to make a paste. Take it out in a mixing bowl. Now add fresh bread crumbs and cornflour to it and mix well. Add all spices and make a soft dough. We can add more cornflour if needed. Keep this dough in refrigerator for 10 min.
Now make balls out of it. Take a ball in your palm and flat it. Now place cheese in the center and close the ball.
Now heat oil in a pan and fry these balls. Yummy and cheesy balls are ready to serve.
