Hey, that's almost enough for something quite delicious!
Never mind if you don't have porcini, use any dried mushrooms. No cured meat leftovers? What about that chicken drumstick from last night? Shred it up and toss it in. Maybe your greens are already cooked, hiding in a tiny take-out box. Skip cooking them in the pasta water and warm them in the chicken broth instead.
This is all about using what you have.
Quick Lunch Pasta with Greens, Porcini and Meats
1/4 pound dry pasta
1/4 cup dried mushrooms, crumbled to bite-size
1/2 cup cooking greens (kale, collards, chard, spinach, or turnip greens), chopped to bite-size
1/4 cup chopped cured meat (speck, prosciutto, pancetta, or bacon*)
1/4 cup chicken broth, warm
Freshly ground black pepper
Boil enough water to more than cover pasta. When water is boiling, ladle out enough to cover mushrooms in a small bowl and set aside. Add a dash of salt to the boiling water and cook pasta to within 1 minute of being done. Add the greens, drain, and toss with remaining ingredients.
*certain cured meats like bacon and pancetta should be lightly sautée in a small skillet before adding to the dish, speck and prosciutto can be eaten as they come from the market. If it's something you serve on a cheese plate, it doesn't need to be cooked.
