Cook the pasta in a large pan of salted boiling water until al dente (check the instructions on the packet for best results). Drain the pasta, rinse in cold water, drain again, then tip it into a large bowl.
Cut the cherry tomatoes in half. Halve and stone the olives and roughly crumble the Feta. Add the halved tomatoes to the pasta and sprinkle with sea salt. Add the olives, feta and spinach and drizzle with the lemon-infused olive oil. Add the pine nuts and basil and toss gently before serving.
