Preheat oven to 450°F.
Empty the bag of kalettes onto a sheet tray. Dress with olive oil, salt and pepper. Roast in the oven for 10-12 minutes, or until crispy and brown on the edges.
Bring a pot of water to a boil for the pasta.
In sauce pot over medium heat, heat oil, 3 turns of the pan. Add anchovies and melt into oil; add garlic, chilies, onions and stir 5 minutes to soften. Add meat and brown and crumble then add paste, thyme and bay. Deglaze pot with vermouth or wine and reduce until almost evaporated. Add stock and passatta, and stir in parsley. Simmer at low bubble for 20 minutes.
Salt boiling water and cook pasta to al dente, 7-8 minutes. Add about 1 cup starchy water to sauce then drain pasta and toss with sauce to coat. Serve in shallow bowls garnished with a drizzle of EVOO and some cheese, if you like.
