Here's how:

1 Cook spaghetti in a large quantity of boiling salted water until just tender. Drain, leaving a little of the cooking water clinging to the pasta. Heat oil in a large heavy-based saucepan, add the onion and garlic and cook on low, stirring, for 2 minutes. Add beans to the pan and cook, stirring, for 1 minute.

2 Add spaghetti, juice and rind to pan and toss until combined and heated through. Add olives, pine nuts and peas, toss until combined and cook for 1-2 minutes. Crumble feta over and toss. Serve immediately with cracked pepper.
