Fill a large pot 3/4 full with water and bring to a boil. Add the pasta and cook until al dente (tender), 10 to 12 minutes, or according to the package directions. Drain the pasta thoroughly.
In a large skillet, heat the olive oil and garlic over medium heat. Add the garbanzos and vegetable broth. Stir until warmed through. Add the raisins and spinach. Heat just until spinach is wilted, about 3 minutes. Don't overcook.
Divide the pasta among the plates. Top each serving with 1/6 of the sauce, 1 teaspoon Parmesan cheese and peppercorns to taste. Serve immediately.
