Peel the skin from the plantains and steam it in a pressure cooker. Cut the steamed plantains into thick round slices. Add little water to the red chili powder, turmeric powder & salt and make into a paste. Put the crushed garlic into the paste. Coat the plantain slices evenly with the spice paste.
Heat the oil in a wide pan and fry the spiced plantain until both the sides turn golden brown. Serve hot.
