Hasty repast is a phrase that refers to a quick and hurried meal. Synonyms for this phrase include fast food, on-the-go meal, quick grub, express eatery, grab-and-go food, snack attack, speedy sustenance, drive-thru dining, rapid refreshment, and instant nourishment. These phrases imply that the meal is consumed quickly and without much thought or planning. Whether it's a fast-food burger, a convenient store snack, or a microwaved meal, a hasty repast is often the result of a busy schedule or lack of time. While these meals can be convenient, they are not always the most nutritious or satisfying, so it's important to balance convenience with healthy choices.
