All of what you say is true, but besides the Nopales, have you ever tried the cactus pears?
OMG I love those prickly cactus pears. However, I can handle its seeds. LOL There is an empty lot nearby where there are cactus and sometime in the Summer it bears it fruits. I will go over and grab some, just love eating them but I hate swallowing the seeds so I spit it out. I’m thinking perhaps maybe juicing it and remove the seeds thru a strainer.
