Pickled green beans, also known as dilly beans, are crisp, tangy, and flavorful green beans that have been preserved in a vinegar-based brine with seasonings. They are typically made by soaking fresh green beans in a mixture of vinegar, water, salt, and spices like garlic, dill, mustard seeds, and red pepper flakes for extra heat.
 
The pickling process gives the green beans a zesty, slightly sour taste while maintaining their crunch. They make a great snack on their own, a garnish for Bloody Mary cocktails, or a tangy addition to salads, charcuterie boards, and sandwiches.
