When someone asks me what to do with an unusual leafy green, I invariably answer, “Sauté with a little garlic or onion.” It really is that simple—and delicious. And it works for any kind of green— from spinach to collards to wrinkled, crinkled, crumpled cress. NOTES: Be sure to use the stems from your greens as well as the leaves—if they’re from a local farmer they will almost always be as tender as the greens. If not, add them to the pan first and cook for a few minutes before adding the leaves.
