Ihave created a new sandwich. the main ingredients are an avocado, a cream sauce, lettuce and/or red fish. firstly, you should wash all the vegetables and clear the avocado. take out of the fridge toastes. you can either dry them or not. wrap the fish in lettuce and put between two slices of bread. don't forget to add some cream sauce in it! it looks very delicious and tasty! this is also appropriate for the vegetarians. such a sandwich tastes amazing in combination with tomato's or citrus's juice.
