Green beans with caramelised shallots

Instructions

1. Steam green beans until tender, about 5 minutes. Run under cold water for 30 seconds; set aside.
2. Mist a non-stick frying pan with cooking spray and heat gently. Add shallots and cook, stirring often, until golden brown, about 5 minutes (add a little water if necessary to prevent burning). Add green beans and toss until hot; season with salt and pepper, sprinkle with lemon zest and serve.
