Boil the orecchiette and broccoli rabe together in well salted boiling water.
Meanwhile, in a large skillet, lightly sauté the garlic, chili pepper and anchovy fillets in olive oil. Turn off the heat.
When the orecchiette and broccoli rabe are done, transfer them and the broccoli rabe with a slotted spoon into the seasoned oil.
Simmer everything together, mixing as you go, until the pasta and broccoli rabe are well seasoned by the oil. The broccoli rabe should partially disintegrate into a kind of ‘sauce’.
Taste for seasoning and add salt to taste, if need be. Serve piping hot, drizzling a bit more olive oil on top of each portion if you like. This is not a dish that calls for any kind of grated cheese.
