One of the most typical dishes in Costa Rica is Arroz Con (fill in the blank). It can be chicken, beef, pork, or shrimp. But most commonly it is made with chicken, because its affordable and many folks grow chickens in their backyards!
This is my take on Arroz con Pollo - or Chicken with Rice. My housekeeper has shared her lunch with me on many an occasion, and it is always wonderful. Last week, I finally asked her how to make it and she rattled off directions. I don't know if I captured everything or not, but we think it tastes pretty good for a first try.
This recipe includes a sauce called Lizano. I'm told it can be found in the hispanic section of some grocery stores in the States, or from specialty online retailers. I don't know because I never knew this sauce until we moved to Costa Rica. If I find a subsitution or a source, I'll edit this recipe to include the information.
Update: Couldn't find a source, but the closest you may come is Worcestershire sauce. Just go easy on it, as Lizano is not as strong tasting as Worcestershire.
