When my kids were younger I would make cactus salad for them. They loved it. This recipe is pretty close to the one I made. I would add a few chopped Jalapeno or Serrano chilies and some Anejo cheese to the salad. Lime works as well as vinegar in this salad, maybe better, but that's a matter of taste. Rinse the cactus well before adding it to your salad to get rid of the slime.
