Mayan squash
 

If you ever find this stuff, buy it; looks like a little pumpkin with alternating light- and dark-green vertical stripes. Has a kind of avocadoey taste, and is good enough to serve raw, in salads or with oil and vinegar.

If you want to cook it, slice it then then nuke it in the microwave for three or four minutes. Take it out, toss it in olive oil, and liberally sprinkle shredded parmesan or romano on top. YUM!
