The pinto bean (/ˈpɪntoʊ/) is a variety of common bean (Phaseolus vulgaris). In Spanish they are called frijoles pintos, literally "painted bean" (compare pinto horse). It is the most popular bean by crop production in Northern Mexico and the Southwestern United States, and is most often eaten whole (sometimes in broth), or mashed and then refried. Either way, it is a common filling for burritos, tostadas, or tacos in Mexican cuisine, also as a side or as part of an entrée served with a side tortilla or sopaipilla in New Mexican cuisine.
