Subway is an American fast-food restaurant franchise known for its customizable submarine sandwiches, commonly referred to as "subs" or "subway sandwiches." Founded in 1965, Subway has grown to become one of the largest restaurant chains globally, with thousands of locations in numerous countries. At Subway, customers have the option to build their own sandwiches by selecting from a variety of freshly baked bread, meats, cheeses, vegetables, and condiments. This customization approach allows patrons to create sandwiches tailored to their preferences and dietary requirements. In addition to subs, Subway's menu includes salads, wraps, and other quick-service items. The company places a strong emphasis on promoting healthier options and has worked to provide low-calorie and nutritious alternatives to traditional fast food.
