If you're a native Texan, then it's likely that you've seen Prickly Pear Margaritas, but have you ever attempted to make them yourself? They're actually very easy (and oh-so-yummy!)
The Fairy Godmother Prickly Pear Margarita
6 parts Tequila blanco
1 part Paula's Texas Orange
2 1/2 parts lime juice
3 parts prickly pear syrup (found it in the syrup section at Spec's Liquor)
Pour over ice and serve!
