The costillas en salsa verde from La Nopalera was delicious. That's ribs in green sauce. There's also some squash cooked with the ribs.
As you might expect, it comes with rice and beans. The cost? $7.00
La Nopalera isn't really a restaurant. It's a Mexican grocery. They do have a table or two and a counter, though. It's a wonderful place with great home style cooking. The specials, like this, are available for lunch.
