The piperade is a culinary ingredient from the Basque region of France. It is a preparation based on onions, peppers and tomatoes, generally cut into small dice. You can add garlic, chili and thyme to flavor the piperade. The piperade is often used as a basis for many recipes, such as omelettes, pies or dishes in sauce. It can be consumed hot or cold, with meats or grilled fish, or simply on a toast like tapenade.
