Poke is a traditional Hawaiian dish that is made with small pieces of fresh and raw fish or seafood, which are combined with finely chopped vegetables, herbs, condiments, and seasonings. Although traditional poke uses either ahi tuna (yellowfin tuna) or octopus, the variations on this dish are endless these days, including poke with salmon, mussels, crabmeat, or oysters, as well as vegetarian versions with diced avocados.

Typical ingredients apart from the raw fish or seafood include sweet onions, garlic, shallots, scallions, sesame seeds, seaweeds, candlenuts, limu (brown algae), soy sauce, honey, sesame oil, red pepper flakes, and Hawaiian sea salt. The creation of poke has been attributed to local fishermen who used to combine freshly-caught small reef fish with few seasonings such as sea salt, candlenuts, limu, and seaweed for a filling snack. 

BBQ shrimp is a traditional dish from New Orleans. Despite the name, it has nothing to do with barbecue – instead it's either cooked on the stove or in the oven. The dish is made with large fresh shrimp (shells on), butter, lemon juice, hot sauce, garlic, and Worcestershire sauce.

The combination is baked or cooked on the stove, and it's then traditionally served as an appetizer. BBQ shrimp are typically served with crusty french bread on the side to mop up the juices.

Tuna tartare is an elegant starter originating from Los Angeles. The dish is made with a combination of raw tuna, avocado, egg yolks, green peppercorns, capers, chives, tarragon, mustard, olive oil, lemon juice, salt, and pepper. It was invented in 1984 by chef Shigefumi Tachibe at the Chaya Brasserie when a few customers came in wanting beef tartare, but one of them didn't eat beef, so the chef tried tuna, and it was an instant success.

Nowadays, it's usually served as a visually attractive appetizer with crackers or toast.

Flaming saganaki is an American appetizer originating from Chicago's Greektown. Essentially, it's a different way of preparing saganaki – a dish that's originally from Greece, made by frying cheese in a small pan. Flaming saganaki was invented in 1968 at The Parthenon restaurant – after it has been fried, the cheese is flambéed with Metaxa or Ouzo and the flames are extinguished with a squeeze of lemon juice.

The cheese used in this dish is usually sheep's milk feta, halloumi, graviera, kasseri, or kefalotyri. This appetizer is traditionally prepared tableside.

Garlic knots are a traditional American type of garlic bread that's believed to have originated in Brooklyn or Queens. They're most commonly found in New York City's pizzerias. These soft and chewy knots are usually made from bread or pizza dough that's rolled and pulled into knots.

The knots are brushed with a mixture of crushed garlic, olive oil, and chopped parsley, but there are many variations with additional ingredients such as oregano, butter, parmesan cheese, or black pepper. Garlic knots are served warm, accompanied by warm marinara sauce, and they're often served free of charge with large orders in pizzerias.

Dungeness crab cake is a specialty from Washington that features the succulent meat of the Dungeness crab, a crustacean inhabiting the waters of the Pacific Ocean on the West Coast of North America. This dish is typically made by combining Dungeness crabmeat with mayonnaise, red bell peppers, celery, onions, herbs, panko breadcrumbs, seasonings, and eggs, and then shaping the resulting mixture into round cakes.

The crab cakes are rolled in additional panko breadcrumbs and fried or baked until crispy. The meat of the Dungeness crab is renowned for its sweet flavor and its delicate texture. The dish is typically served as an appetizer, a snack, or a main meal for lunch or dinner.

Charbroiled oysters is a traditional dish originating from New Orleans. In order to make the dish, freshly shucked Louisiana oysters on the half shell are placed on the hot grill and cooked in their own juices until bubbling and the edges start to curl.

The oysters are topped with a sauce consisting of butter, garlic, parsley, salt, pepper, cayenne, lemon juice, and grated Pecorino Romano. Once the sauce has started to bubble, each oyster is sprinkled with grated Pecorino and garnished with minced parsley. 

Originally invented in New Orleans' French Quarter, these oysters are baked in their shells with bread crumbs, grated cheese, onions, mushrooms, shrimp, wine, and a buttery roux. The oysters are baked until lightly browned, then served immediately, preferably garnished with chopped green onions and lemon wedges.

This elegant appetizer is served in many fine dining restaurants in New Orleans, including the famous Antoine's and Arnaud's.

Mozzarella sticks are one of America's favorite cheesy snacks consisting of battered, breaded, and deep-fried pieces of mozzarella cheese. Although they are traditionally served as an appetizer with marinara sauce, these cheesy sticks can also be paired with plum sauce, honey mustard sauce, raspberry sauce, Ranch dressing, or barbecue sauce.

Mozzarella sticks were not common before the late 1970s and the early 1980s, and some food experts believe that they were first served in sports bars and bowling alleys.
