Step 1

In a pot of salted boiling water, cook the orecchiette until al dente. Drain, reserving 3/4 cup of the cooking water.

Step 2

Wipe out the pot and heat the olive oil in it. Add the sausage and cook over moderate heat, breaking up the meat with a wooden spoon, until browned and nearly cooked through, 7 minutes. Add the onion and cook, stirring occasionally, until softened, about 3 minutes. Add the chickpeas, orecchiette and reserved cooking water and toss over moderate heat until the pasta is hot and coated in a light sauce, about 2 minutes. Stir in the mint and lemon juice and season with salt and pepper. Spoon the pasta into bowls and serve with yogurt.
