How to Make It
Cook the whole-wheat pasta in boiling salted water, according to package directions.
In a large frying pan, heat the olive oil over medium high heat. Add the onion and cook for 5 minutes, or until it begins to soften and brown. Add the chorizo and cook, stirring frequently, for 5 minutes, or until the chorizo is cooked and the onion is nicely browned. Add the chile flakes, garlic and kale and cook until the kale is just barely wilted, about 1 minute. Remove from heat.
Add the cooked pasta to the pan and toss to coat well. Add more olive oil as necessary and generously season with sea salt and freshly ground pepper
