Pepperoncini are small, mild chili peppers that are typically yellow-green in color. They are commonly used in Mediterranean cuisine and are often pickled to enhance their flavor. These peppers have a slightly tangy taste and are usually served in salads, sandwiches, or as a garnish. In addition to their culinary uses, pepperoncini are low in calories and provide some vitamins, such as vitamin C. They are often found in jars in grocery stores, either whole or sliced, making them a convenient addition to various dishes.
