I googled for a cactus recipe, and jumped forward to the 100th page, and came up with this.
Queso Fundido de Nopales
2 cups nopales, scraped, washed and cut into strips
1 cup ground chorizo sausage
1 tablespoon olive oil
2 cups Chihuahua cheese, grated (available in Mexican food stores, or substitute shredded Monterey Jack)
1/2 of an avocado, sliced
That sounds delicious. I may actually have to try one of these recipes someday, and this sounds like a good one to start with.
