Bring 2 inches water in a deep skillet to a boil for broccoli rabe and 1 large pot of water to a boil for pasta. Salt the water liberally.
Simmer the broccoli rabe in water 10 to 12 minutes, then drain. Return the skillet to medium heat with 1/4 cup extra-virgin olive oil. Add garlic and red pepper to the oil and gently cook a couple of minutes, add broccoli rabe and cook 5 minutes more.
While the broccoli rabe cooks, drop the rigatoni into the boiling water and cook until al dente. Just before draining reserve 1 cup starchy liquid.
Combine the ricotta, Parmesan, salami and black pepper, to taste, in a pasta bowl. Add the starchy liquid and stir. Add the broccoli rabe and pasta and toss 2 minutes to coat and combine.
