Arroz con Pollo
Or
Gallo Pinto
Both are fairly easy to make, and good for sharing.
Gallo Pinto is easy just rice and beans and sometimes a bit of condiments
Cook some rice and beans .throw a little beef in it and when the tasters ask tell them it is just a little road,kill .that will get them,
Black beans and rice with hot sauce called lizano salsa.
i have to bring in a typicall food people eat in costa rica and why its important and stuff. something simple, everyone has to try a portion.
