First cut thin slices of cucumber without peeling it.

You need slice three sandwich cut it's edges, mix Mayonise2tbsp in tuna fish with 1/4tsp Black pepper Salt Add to taste.

Mix it place cucumber on a plate in 2lines and put slice on it.put better of tuna fish on it

Then cover with other slice and put sauce on it then place tomato on it. For kids I use green chutney.

Then coverage slice inner side put some ketchup and upper side mayonise cover it so that cucumber stick on it

Cover cucumber in two sides then cut it from center it's really tasty.
