The origin of the chimichanga is hotly disputed. What's not in question is that deep-fried burritos are delicious, and we eat them as often as our diet allows. Our pick is the chimi plate at Valle Luna, a local mainstay for more than 35 years. First, choose your meat; we like the spicy machaca beef, but other options include shrimp, ground beef, shredded chicken, and pork. Next, wait for your meal to show up, a full plate composed of a thick chimichanga topped with house-made Sonoran chimi sauce, plus sour cream, guacamole, rice, and beans. You'll leave stuffed even if you didn't fill up on Valle Luna's chips and salsa earlier in the meal.
