I grew some chokos (aka Chayote, Sicyos edule, christophine, mirliton)
(i.ibb.co)https://i.ibb.co/mHbB9Qn/IMG-8083.jpgOn the taste level - at the bottom of the scale - but a lovely looking fruit and it has dense vegetable matter like a potato so probably lots of nutrients. When harvested small they are tender and taste like mild peas. The ones in the pic are too big because I didn't discover them until late. Seems to be an easy-to-grow plant and if your garden doesn't produce much it's a plant for you as it produces a lot of fruit.
"Chokos in Australia were known as a 'filler' for low-income families during the Great Depression. Given the choko's ability to grow wild and yield plenty of crops, it was seen as a free backyard source of fibre and nutrition."
