I've always loved Tuuuesday. You have to say it like that - TUUUesday.
The thing I love most about Costa Rica is the fresh fruits and vegetables. Granted, when I go to the local market, I don't know what a lot of things are but I am on a quest to learn what it is and how to prepare it. We all know what these are. They're cheap and plentiful here.
So, what is this - a vegetable or a fruit?
The last photo is Sineguelas (Spondias purpurea) or Spanish Plum in English, and is native to Mexico and the western coast of Central and South America.

Comment from reader: "The bottom photo is of pejibaye, or peach palm, and I agree, it smells awful. But it tastes great, so buy & it a try it!
The middle photo is of chayote, which is a squash. You'll find pico de chayote a lot in restaurants, as it's very, very tico. If you like squash, you'll probably like this."
To reader (Erin):I checked out pejibaye and it looks different from the photolink - http://www.hort.purdue.edu/newcrop/cropfactsheets/pejibaye.html
