RE: Pork taco
It's funny that this comes up now. I've been to Anna's Taqueria in Brookline a couple of times recently (typically it's more like a couple of times a year) so instead of getting the steak super burrito I got carnitas for the the first time in years. It came with cheese, red beans, rice, salsa, green hot sauce and sour cream.
I'd forgotten how tasty that roast pork is and how well it holds up to the rest of the ingredients.
