Step 1

Use a zester to remove rind from lemon. (Alternatively, use a vegetable peeler to peel rind from lemon. Use a small sharp knife to remove white pith from rind. Cut rind into very thin strips).

Step 2

Season tuna with salt and pepper. Heat 1 teaspoon of the oil in a medium frying pan over high heat. Add the tuna and cook for 1 minute each side for medium rare or until cooked to your liking. Remove from heat and set aside for 2 minutes to rest. Use a sharp knife to thinly slice.

Step 3

Meanwhile, cook the pasta in a large saucepan of salted boiling water, following packet directions until al dente. Drain well.

Step 4

Heat the remaining oil in the pan over low heat. Add the chilli, garlic, capers and lemon rind and cook for 1 minute. Remove from heat. Add the pasta, pine nuts, parsley and rocket and gently toss to combine. Divide evenly among serving plates. Top with tuna and serve immediately.
