Bring a large pot of salted water to a boil. Add the orecchiette and cook according to the package directions. Drain and toss with 1 tablespoon of the olive oil.
While the pasta is cooking, heat the remaining 1 tablespoon olive oil in a large skillet over medium heat. Crumble the sausage into the skillet, add the crushed red pepper and cook, breaking up the sausage with a wooden spoon, until browned, about 5 minutes.
Pierce the garlic on a fork. Add the orange juice, beans, sun-dried tomatoes and broccoli rabe to the skillet and cook, stirring constantly with the fork, until the sauce is heated through, about 4 minutes. Discard the garlic. Add the orecchiette, Gorgonzola, pine nuts, orange zest and Parmesan. Lightly toss and serve.
