Belgium, often eaten without any side orders. Prior to 1960, the choice of accompanying items was limited to a pickled herring, a large, cold meatball boulet or red-coloured garlic sausage cervela, or a beef or horsemeat stew. Since 1960, these choices include stoofvlees or stoofkarbonade and a wide variety of deep-fried meats, such as chicken legs, beef or pork sticks, minced beef, pork, chicken, or turkey in all shapes (balls, sticks, sausages) mixed with a dosage of fat and condiments to one's preference. An example of an additional on-the-spot preparation is sometimes in Flanders called mammoet speciaal (mammoth special), a large frikandel (curryworst in Antwerp and Flemish Brabant) deep-fried and cut so as to put chopped onion in the V-shaped length and dressed with mayonnaise and (curry-)ketchup. The earliest of the current wide array of sauces, are mayonnaise, fritessaus or sauce pommes-frites ("fries sauce" in English—see the sections on France and the Netherlands) and a local pickle-sauce similar to piccalilli. Though Belgians do not sprinkle vinegar on fries, they may eat them with cold mussels out of the shells preserved in vinegar, entirely different to the national dish with freshly boiled hot mussels served in the shells. Bulgaria In Bulgaria, a serving of fries can be ordered with a covering of sirene, a grated white brine cheese. Canada In Canada, French fries are the main component of a dish called poutine, a mixture of French fries with fresh cheese curds, covered with a hot gravy (usually), hot chicken sauce (much less common), or chicken BBQ sauce (rarely). This dish was invented in rural Quebec in the late 1950s and is now popular in many parts of the country and is served at many fast-food chains. Several Québécois communities claim to be the birthplace of poutine. A variant, "disco fries", may be found in the Northeastern United States, notably in New Jersey. In Newfoundland, "chips, dressing and gravy" (referred to by outsiders as "Newfie fries") comprise French fries topped with "dressing" (turkey stuffing made with summer savory) and gravy. Another variation consists of topping the French fries with either ground beef, hot dogs, dressing and cheese and topped with gravy. Yet another Newfoundland recipe called a "mess" (compare with "poutine") consists of fries, gravy, dressing, and wieners. In Prince Edward Island, "fries with the works" (or FWTW as it is some times called) is a combination of French fries, fried hamburger,
