This is one of the favorite snacks at home. Its very easy, tastes so good and most important is very satiating. I never knew about the concept of open sandwiches until this recipe was introduced to me after marriage. Open sandwiches as the name suggests are open with some toppings on top of the bread. There are hundreds of varieties of them but this one is the first and the only one I have ever tried or eaten. Try to make this one on a sunny day as the taste and the combined flavors of all the ingredients are really refreshing.
