Heat oil in a saucepan, saute the onion till soft.
Add the tomato paste and saute for a couple of minutes.
Add in the mashed tuna and the masala powders and cook on low flame for around five minutes. Add in the cooked sweet corn and mix well.
Make a hole in the center. Break in the eggs. Sprinkle the black pepper over.
Mix vigorously and ensure eggs are completely mixed into the tuna.
Cook for a couple of minutes. Do not cook for too long otherwise the mixture will get too dry.
Warm the pita breads. Cut into two and slit.
Spread mayonnaise as required. Spoon in some of the tuna mixture lavishly. Drizzle chilli sauce over. Repeat for the other piece.
This quantity is enough for making four pita bread sandwiches.
Serve with some salad!
