Step 1Preheat oven to 160°C/140°C fan-forced. Cut calamari in half. Score inside flesh and cut into 3cm pieces.
Step 2Combine flour, salt, pepper and Chinese five spice in a snap-lock bag. Add enough oil to a large, deep frying pan to come 5mm up side of pan. Heat over medium-high heat.
Step 3Add a third of the calamari to flour mixture. Toss to coat, shaking off excess mixture. Cook, turning, for 2 minutes or until light golden. Transfer to a greased baking tray. Place in oven to keep warm while cooking remaining calamari. Serve sprinkled with chilli and green onion.
