Ok so we are back to this! Vers and I have had this conversation before and are apparently never going to agree. Collards, mustard, and turnip greens, are all fine for staples! This is a tried and true diet mix that has been successfully used by keepers, breeders, zoos, and vets for decades for feeding herbivorous lizards. I have personally fed them daily to my 12 year old green iguana as well as my beardies. The reason it is used is because it works. And don't cook the squash, just grate it.
