Here's a recipe from a reader, SarahW, for a simple pasta dish using Swiss Chard (it's been a hot topic of discussion on the Open Threads for a while) and Feta cheese. With greens such as spinach about to come into season on the East Coast, this would make a great spring dish.
Pasta With Greens and Feta
6 Tbsp. olive oil (or less) 4 cups chopped onion 8 cups packed chopped bitter greens (e.g., swiss chard, or swiss chard plus other greens like spinach or escarole) 3/4 to 1 lb penne or other short substantial pasta 1/2 to 3/4 lb crumbled feta cheese salt and pepper
Cook onions about 10 minutes over medium heat. Start pasta water.
Add chopped greens to pan and cook 10-15 minutes.
Cook pasta al dente.
Just as pasta is close to done, add feta to greens mixture (over low heat).
Add pasta to greens mixture, mixture thoroughly while heating for a few minutes.
