Cauliflower Collard Tacos

Normally we don't blog taco nights (aka Friday nights), but these were rather tasty and deserve blogging.  We essentially took the Rick Bayless garlicky greens tacos as our start.  Carmelized some onions while the collards were boiling, then threw the cauliflower in with the greens.  Mixed it together with some frozen tomatillo sauce (not too much, the weren't real saucy), then topped with feta.  Yum.
