Ingredients

Contains: milk, wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Bring a large pot of salted water to a boil. Add the pasta and cook until just tender, about 8 to 10 minutes. Reserve a splash of the cooking water, then drain.

  2. While the pasta cooks, heat the olive oil in a large skillet over medium heat. Add the sliced onion and cook until soft, about 5 minutes.

  3. Stir in the minced garlic, red pepper flakes, capers and anchovy pieces. Cook, mashing the anchovies into the oil, until fragrant, about 1 minute.

  4. Add the diced tomatoes with their juice and the black olives. Simmer over medium-low heat for 5 minutes, stirring occasionally.

  5. Stir in the chopped kale and cover the skillet. Cook until the kale wilts and turns bright green, about 2 to 3 minutes.

  6. Add the drained pasta to the skillet and toss well, adding a splash of the reserved cooking water if the sauce is too thick.

  7. Divide among four bowls and sprinkle with the grated Parmesan cheese before serving.
