Day eight: Grilled mackerel salad

Grilled (or smoked) mackerel with green beans and watercress, spring onion, kale and cannellini beans. Dressing of olive oil, lime, garlic and sesame seeds. Quick to prepare with loads of protein from the fish. Watercress are packed with nutrients such as cancer fighting glucosinolates and carotenoids. Thanks Lilly for sending this one in!
