Christian posted a review of Lucia's Tacos y Mulitas, a mexican joint in Huntington Beach, CA, and he snapped a photo of their menu board, showing "Cactus Omelette"...
I did some growing up in San Diego between 1971-1978, and I had mexican friends across the street. Their mom frequently used cactus in her cooking. I was suprised at the time to see cactus being used, but later on in life I came to understand it was quite common in Mexican cuisine. They called them "Nopales", or "Nopalitos" for the softer baby leaves.
They kept a rabbit pen and a chicken coop, and on Sundays, would pull out a rabbit or chicken, kill it, clean it, and tossed it on this large brick grill they had in their backyard. Their mom would make the corn tortillas and salsa, and she'd pull out a jar of nopalitos, to garnish the tacos. Then we'd sit underneath this old pepper tree (or willow tree) and have rabbit tacos.
And quite good they were. The nopalitos added some "texture" to the tacos, and a bit of taste.
Cactus wasn't bad, but not necessarily what I'd call "good". It's something you'd have to grow up eating to enjoy.
I'll have to stop by at this Lucia's Tacos y Mulitas the next time I'm in that area, and try the omelette.
I also mentioned, "Cactus flavored chewing gum", awhile back on Strange New Products.
