fried onions, gravy (usually beef), peas, and optionally mushrooms. Other common toppings include green onions, tomatoes, carrots, sour cream, and grated cheese. In the Ottawa Valley, french fries are sold from trucks known as "chip wagons," and fries are available topped with melted butter. It is also customary for the server to allow the customer to add seasonings like salt, pepper, and vinegar halfway through filling the container. Finland In Finland, french fries (ranskalaiset perunat) are colloquially known just as ranskalaiset (literally, "the French"). In colloquial use, this is sometimes shortened even further to ranet or ranut, which unambiguously only refers to french fries. A traditional way of serving accompanied fries at food carts (grilli) is makkaraperunat (literally, "sausage potatoes"), a dish consisting of deep-fried slices of sausage and crinkle-cut fries mixed together and usually served in either a paper or styrofoam tray. The dish probably originated in the early 1960s. Today, makkaraperunat is mainly considered a late-night snack and is usually not served outside of food carts or gas stations. At fast food chains such as McDonald's, Burger King or the indigenous Hesburger, ketchup is always provided. Some chains also offer complimentary Finnish or American style mustard as well as packets of grillimauste, a type of barbecue rub. In kebab shops, fries are often partly or entirely covered in tomato-based and/or yoghurt-based kebab sauces and döner kebab strips. French fries are also used as sides for hamburgers, steaks and deep-fried meats at the ubiquitous American style restaurants and gastropubs in Finland. Crinkle-cut fries are seen as old-fashioned and associated with food carts or home-cooking, while straight-cut fries are seen as more modern. France In France, a common dish is fries and a steak. French fries are also popular as a side dish to kebabs, roasted or fried chicken, and hamburgers. The fries are often accompanied by ketchup, mayonnaise, Dijon mustard, and sometimes a vaguely béarnaise-like sauce called "sauce pommes frites" (found also under the same name and with a similar form in French-speaking Belgium, and in Dutch-speaking Belgium and the Netherlands as fritessaus), which is available at local McDonald's restaurants and in bottled form in supermarkets. Iceland In Iceland, french fries are served either salted or seasoned with a special blend of spices (including salt, sugar, onion powder, garlic powder, black pepper, MSG, and various other seasonings) marketed as French Fry Mix (kartöflukrydd), and accompanied by cocktail sauce or
