Heat oil in a medium size sauté pan on medium flame. Add onions, curry leaves and cook till they are lightly browned around the edges. Add the stuffed eggplants, water and gently mix. Cover and lower the heat. Cook until the eggplants are tender, about 10~12 minutes. Stir occasionally to make sure eggplants cook evenly on all sides.
2 tablespoons Oil, 1 Medium Onion, finely chopped, ¼ cup Water, plus more if needed
