Same here, but I must admit to cheating. Trader Joe's (popular market here in SoCal and other locales) sells chunks of cooked pork for carnitas. All that's necessary is a couple minutes in the microwave and then you just shred the meat and you're good to go -- with cilantro, salsa, maybe some diced avocado, and tortillas.
But now you've got me wanting a Margarita (on the rocks), so I pray I have a lime in the fridge. If not, I'll go with the old standby for spicy food -- a nice, fairly dry Gewurztraminer.
