Step 1
Cook the pasta in a large saucepan of boiling water following packet directions or until al dente. Drain, reserving ½ cup (125ml) of cooking liquid.
Step 2
Meanwhile, heat oil in a large, deep non-stick frying pan over medium-high heat. Cook half the chicken, stirring, for 3 mins or until golden brown and cooked through. Transfer to a plate. Cover with foil to keep warm. Repeat with the remaining chicken.
Step 3
Add the tomatoes to the pan and cook for 3 mins or until the tomatoes begin to collapse. Remove from heat. Transfer tomatoes to a separate plate.
Step 4
Return chicken to pan with the pasta, pesto and reserved cooking liquid. Season. Toss to combine. Stir in the rocket. Top with the tomatoes.
