Orecchiette with Shrimp, Arugula, and Cherry Tomatoes
If you want to cook the pasta ahead, toss it with the olive oil, and refrigerate for up to two days. Cook the shrimp up to a day ahead, and add it to the pasta. Combine the tomatoes, juice, olives, and spices early on the morning of the party. Leave this mixture out at room temperature so the flavors will meld. Toss everything together just before guests arrive.
