Step 1
Preheat the oven to 180C fan-forced (200C conventional). Line an oven tray with baking paper and place the broccolini on the tray.
Step 2
Combine the butter, anchovy, chilli and lemon rind in a small bowl and season with pepper.
Step 3
Spoon the flavoured butter over the broccolini and drizzle with lemon juice and 2 tablespoons of water.
Step 4
Place broccolini in the oven and roast for 15 minutes, or until it is tender and starting to char.
Step 5
While the broccolini is roasting, heat a large non-stick frying pan over high heat. Brush the lamb with oil, add it to the pan and cook for 6-8 minutes, turning halfway through.
Step 6
Place the lamb on the tray with the broccolini, and roast for 10-15 minutes, for medium. Set aside and rest for 5 minutes.
Step 7
Slice the lamb and toss it with the broccolini and rocket leaves, and drizzle over the pan juices. Sprinkle with slivered pistachios and serve.
