Place the chopped parsley, garlic, chilli flakes and vinegar in a food processor and process until finely chopped. Add 2 tablespoons of the olive oil and process until well combined.
Heat a lightly greased frying pan over medium-high heat. Add the chicken and cook for 4-5 minutes each side or until golden brown and cooked through. Transfer to a plate.
Bring a large saucepan of water to the boil. Cook the beans and baby broccoli for 1-2 minutes or until tender. Drain well. Return to the saucepan. Drizzle with remaining oil and lemon juice and toss to combine.
Meanwhile, heat the rice following packet directions.
Divide the rice and baby broccoli mixture among serving plates. Arrange the chicken over the rice and drizzle with the chimichurri. Serve with lemon wedges.
