These are chokos-at least that is what they are called in New Zealand and Australia.
"The chayote (Sechium edule), also known as christophene, vegetable pear, mirliton, alligator pear (South Louisiana), choko(Australia, New Zealand), starprecianté, citrayota, citrayote (Ecuador and Colombia), chuchu (Brazil), chow chow (India) Sayote (Philippines) ,güisquil (Guatemala, El Salvador), or pear squash, iskus (इस्कुस) (Nepal)" -Wickipedia
They are native to Mesoamerica and to be honest I don't know why they have them here. Asian's use them in stir fry. They are a ground plant like a mellon or squash and I haven't eaten them before. I am going to try it though and let you know what I come up with. :)
How This Started and My Hope For This Experiment
My Husband and I are both big fans of Jamie Oliver. For Christmas I bought him Jamie's cookbook "Jamie's 30 Minute Meals: A Revolutionary Approach to Cooking Good Food Fast". As I read the preface of his cookbook I was inspired by his ideas. He felt that he was spending too much time cooking during the busy week and doing too much clean up. So he decided that for the week night meals there needed to be something quick and still healthy and yummy. He and his team did a lot of work and made the "30 Minute Meals". He has explicit directions for step by step getting the meal done in 30 min. He tells you what to do first, second, and third so that you have all dishes going at the same time, instead of making it dish by dish. Since we aren't doing once a month cooking right now I was captured by this idea and dying to start trying. I have been spending way too much time in the kitchen during the week and can't wait to be able to prepare good meals fast. My husband was all for it since he loves to eat great food and has a very particular palette. He will be making some of the meals on weekends when he isn't working because, this is after all, his cookbook :)
