A fish sandwich is a popular sandwich featuring fried or grilled fish fillets, typically served on a bun with toppings like tartar sauce, lettuce, and pickles. It is a staple in coastal cuisines worldwide, from American fast-food chains to traditional British fish finger sandwiches.
High in protein from the fish, but can also be high in fat and carbs depending on the frying method and bun type. A typical serving provides omega-3 fatty acids and roughly 400-600 calories.
The fish sandwich has evolved from a simple seaside snack to a global fast-food icon, with regional variations like the Japanese 'fish burger' or the Scandinavian 'fiskesandwich' reflecting local tastes and fishing traditions.
