Combine chicken mince, onions, garlic, ginger and oil in a bowl.
Heat a wok over high heat. Stir fry chicken mixture until golden brown and cooked through. Remove from heat and stir through coriander.
Divide mixture among lettuce leaves and top with avocado. Sprinkle with chilli.
TIPS - You could use pork or turkey mince in this dish for a change. We used iceberg lettuce leaves, but you could use butter lettuce or even Chinese cabbage, trimmed into cup shapes.
