Wash the tripe well. Cook it in sufficient water with the cudla dhal and a little salt in a pressure cooker till soft. Drain and keep the soup aside. Heat the oil in a pan and sauté the onions lightly. Add the sliced tripe, ginger, garlic, salt, turmeric powder, chilly powder, cumin powder, coriander powder and pepper powder and mix well. Add the soup. Cover and simmer on low heat till the gravy thickens. Serve hot with rice or bread.
