A "light repast" often refers to a meal or snack that is not too heavy or filling. There are several synonyms that can be used to describe this type of meal, including "snack," "bite," "nibble," "refreshment," "appetizer," and "teatime treat." Each of these synonyms emphasizes the small or light nature of the meal, and can be used in a variety of contexts. Whether it's for a mid-day pick-me-up or as part of an elegant evening event, a light repast is a great way to enjoy food without feeling too full or weighed down.
