My house in Tucson has a couple of prickly pear cacti in the front yard, and I used them in omelets with chorizos. The fruit is pretty darn good, too, except the birds always beat me to it.Interesting. I've never had prickly pear and did not know that was a thing people ate just grilled like that! But I can image it's yummy.
One of my all time favourite hot sauces (and I've tried over 100 different kinds at this point) is Marie Sharp's Green Habanero…
First ingredients are indeed green habaneros followed by nopal prickly pear cactus. It is incredible AND has no salt added which is getting to be an important consideration for me.
