Collards anyone?

I’ve learned that Springfield, Illinois just doesn’t garden like the North. The flowering dogwoods everywhere were a clue. Broccoli and brussels sprouts definitely sulk, so on a whim this year I rescued a dozen runty, overstressed collard plants from an end-of-season nursery and put them in the garden I tend for my employer.

They are looking beautiful! Now, how do I go about preparing them for a vegetarian? Local wisdom is to boil them with a pork hock or smoked turkey neck. Anyone have a suggestion for preparation? I’m leaning towards a light saute with onions and soy sauce for starters, but don’t even know if I’m supposed to be picking the young leaves or the old leaves…
