A salteña is a type of baked empanada from Bolivia.
Salteñas are savory pastries filled with beef, pork or chicken mixed in a sweet, slightly spicy or very spicy sauce, and sometimes also containing peas, eggs, olives, raisins, potatoes and other ingredients. Vegetarian salteñas are sometimes available at certain restaurants.
Typically salteñas can be found in any town or city throughout the country, but each area has its variations; Cochabamba and Sucre claim to have the best version of this snack, and many will go out of their way to try the variation from Potosí. In La Paz, it is a tradition to enjoy salteñas as a mid-morning snack, although vendors often start selling salteñas very early in the morning. The pastries are sold anywhere from 7am to noon; most vendors sell out by mid-morning.
