The word “chayote” is Spanish, borrowed from the Nahuatl word chayohtli. Chayote was one of the many foods introduced to Europe by early explorers, who brought back a wide assortment of botanical samples (Wikipedia)
My mom makes awesome stuffed thorny chayotes, I’ve loved them since I was a kid, the hard part is dealing with the thorns! Pretty much she just boil them, cut them in half, hollow them, mix the flesh with canned crushed tomato and top it with parmesan cheese, breadcrumbs and some butter.
Here are some pics.
