Bring a large pot of water to boil. Salt the water and cook pasta according to package directions.
In a large skillet, heat the olive oil over medium-high heat. Add the shallot and garlic. Cook until tender, about 4-5 minutes. Add a dash of crushed red pepper flakes. Stir in the chopped kale. Stir and add the lemon zest and lemon juice. Cook until kale leaves are wilted and tender.
Carefully drain the pasta. Return to pot. Crumble the goat cheese over the hot pasta and stir until creamy. Add the kale/lemon mixture. Season with salt and black pepper, to taste. Serve immediately.
