A veggie sub is a type of sandwich that primarily features a variety of fresh vegetables as its main filling. Common ingredients include lettuce, tomatoes, cucumbers, bell peppers, and onions, often served on a long roll or hoagie bread. Many people enjoy adding condiments like mayonnaise, mustard, or vinaigrette to enhance the flavor. Veggie subs are popular among vegetarians and those seeking a healthier meal option. They can be customized to suit individual tastes, allowing for the addition of ingredients like cheese, avocado, or sprouts. This versatility makes the veggie sub a favorite choice in many sandwich shops and delis.
