There are spots where you can get a great beef-cheek taco; places where the asada burritos are as big as your head. But there's only one Mexican restaurant in town where our favorite plate is, technically, a vegetarian one. That restaurant is Rosa Linda's, where the cactus tacos keep us coming back year after year. The tough outer petals are de-spined, peeled, shaved and cooked down until they're as tender and sweet as those canned green beans your mom used to make you eat as a kid. But these are much, much better. Add a little salsa or maybe just a squeeze of lime, and you've got the very best way to eat your vegetables.
