Is there a greater leafy green than Swiss chard? It's more versatile than Meryl Streep. It's edible both raw and cooked. It's packed with vitamins A, K, and C. Plus, it's related to the sea beet, which is really fun to say out loud. Bitter, but not so much as broccoli rabe, chard is lovely own its own, in soups, or as part of a bigger recipe.
'turkey sausage' on Serious Eats
I stumbled over Mark Bittman's Broccoli Rabe with Sausage and Grapes by pure serendipity, while researching beets in How to Cook Everything. The necessary produce was already crowding my crisper drawer, and the oil and seasonings were standing ready in the pantry. Even better, a trip to the freezer revealed two links of sweet Italian turkey sausage, which, when subbed in for their pork equivalents, would lighten the meal considerably.
