Cut squid tubes in half lengthways. Pat dry with paper towel. Using a small, sharp knife, score the inside of squid hoods in a criss-cross pattern. Cut into about 4 cm pieces.
Place squid pieces in a large bowl. Add spice blend. Toss to coat.
Heat an oiled, non-stick frying pan or barbecue flat plate over a high heat. Stir-fry the squid in three batches for 1-2 minutes, or until browned and tender. Transfer to a baking tray. Cover loosely with foil to keep warm.
Arrange salad leaves over a large serving plate. Top with mango and squid. Sprinkle with macadamias.
Serve with lime wedges, if desired.
