Scandinavian and German communities who have fishing traditions use pickled herring as their preferred filling. The high herring catch rates during past times made pickling the best method to preserve fish from becoming spoiled. The open-faced Danish smørrebrød sandwich uses pickled herring as its most famous sandwich ingredient because it combines buttered rye bread with pickled herring and egg and salad vegetables. Pickled herring serves as a popular sandwich ingredient across Germany, Sweden, Norway, Finland, Poland, and Canada.
Lamb
The Middle East has become known for its delicious dishes that use lamb. The dish of lamb shawarma includes fresh meat shaves, which chefs grill and wrap inside Arabic flatbreads together with vegetables, pickles, and tahini sauce. The dish contains delicious lamb, which people eat with pita bread and tzatziki sauce, just like they do with Greek gyros. The 'boat' sandwich of Iceland uses lamb as its main ingredient, and people usually eat it with crispy onions, pickles, and mayonnaise.
Smoked salmon
In the 19th century Jewish immigrants introduced the world to smoked salmon, which they created through brining and smoking methods that enabled fish preservation during the pre-refrigeration era. Jewish New Yorkers began using smoked salmon as a bagel topping shortly after. At that time people in the UK began to develop a taste for smoked salmon sandwiches. The sandwich filling remains popular today because it complements cream cheese and dill and lemon and capers and cucumber.

Cheese savory
The British flavor combination that people in northeast England know better than others is this particular combination. The basic cheese sandwich transforms into a delicious sandwich through its filling, which contains grated cheese and carrot and finely diced onion and either salad cream or mayonnaise. The dish contains both crunchy elements and colorful components, and it delivers a tangy flavor combined with a creamy taste, which restaurants serve inside a stottie cake that consists of a round, flat loaf with a chewy texture.
Coronation chicken
The British people have a strong passion for curry, which explains the high demand for this specific sandwich filling. Coronation chicken exists as a basic dish that combines chicken breast chunks with curry powder in a creamy sauce; various recipes add dried apricots and sultanas and diced nuts and mango chutney to the dish. Chef Rosemary Hume created the dish for Queen Elizabeth II's 1953 coronation, which gives the dish its name, 'coronation.' The dish has appeared in sandwich form on café menus and supermarket shelves and buffet tables throughout Britain since then.
Vegemite
Vegemite serves as the Australian equivalent of peanut butter and jelly, which Americans use as their national sandwich. Australian scientist Cyril Callister developed Vegemite in 1923 as a substitute for the British yeast extract product Marmite. The sandwich, which appears in the lyrics of "Down Under" by Men at Work, represents an essential element of Australian culture because it serves as a birthday party food for children. The basic sandwich consists of butter and Vegemite spread on bread, but people also create gourmet versions that contain avocado and cheese.
Pâté
Pâté serves as a rich and luxurious spread that improves the quality of sandwiches through its various meat, vegetable, and spice components and its selection of matching side dishes. Vietnamese bánh mì turns the classic combo of pâté and French bread into a sandwich, adding in pickled veggies, herbs, and chilies. The open-faced sandwich known as smørrebrød, which represents Danish cuisine, typically features pâté as one of its standard toppings.
Chicken salad
The chicken salad sandwich combines three elements: chicken meat with mayonnaise and salad ingredients. The first American version of this filling originated from a meat market in Rhode Island during 1863 when its owner combined leftover chicken with grapes, mayonnaise, and tarragon. Today the popular filling more commonly includes finely chopped celery and apple and red onion and mustard.
Cucumber
The cucumber serves as a basic sandwich ingredient because of its crisp texture and light flavor. The dish exists as an essential element of British afternoon tea service because it comes in tiny finger sandwich portions, which people across the United States continue to enjoy. The dish reaches its maximum taste when people prepare it as a sandwich using soft white bread without crusts and butter as the only spread. The common combinations feature cream cheese and dill together with Marmite as a secondary choice.
Lobster
Lobster makes a perfect sandwich ingredient because it has a light texture, it contains substantial meat, and it has a slightly sweet flavor. The dish, which originated in summer, has become a popular menu item for seafood shacks and restaurants and food trucks that operate throughout New England and the Canadian Maritime provinces. Fishermen used to eat the meat because they wanted to keep lobster from becoming waste, but now it appears as a gourmet dish that restaurant diners can enjoy in two forms.
