Pimientos del piquillo rellenos are a popular Spanish dish consisting of piquillo peppers that are stuffed with various fillings. Piquillo peppers are small, sweet red peppers from the Navarra region of Spain, known for their vibrant color and slightly smoky flavor.

The piquillo peppers are usually roasted and then peeled, which gives them a tender and slightly charred flavor. After being prepared, the peppers are stuffed with a variety of fillings. Common fillings include seafood, such as cod or shrimp, ground meat, or a combination of vegetables and cheese.

Once stuffed, the peppers are often arranged in a baking dish and covered with a sauce. A popular choice is a béchamel sauce, which adds a creamy texture and rich flavor to the dish. The dish is then baked until the peppers are heated through and the sauce is bubbly and slightly browned.

Pimientos del piquillo rellenos are typically served as a tapa or appetizer, but they can also be part of a main course.
