Heat a pan with oil and add the cumin seeds. When they begin to sizzle, add garlic and let cook for a minute until aromatic. Add hing and dice potatoes.
Saute for 2 to 3 mins. Cover and cook until fork tender, just cooked but not mushy. If required, sprinkle some water to help cook the potatoes well.
Add red chili powder, half of the salt, turmeric, garam masala and green chilies. Saute for a minute and add the cabbage.
Stir fry on a medium high heat until the cabbage is done to your liking. I prefer to keep the cabbage crunchy yet slightly tender. It takes me 3 to 4 mins only.
Sprinkle rest of the salt and turn on the flame to high. Saute until the salt is mixed well. Garnish with coriander leaves.
