Start by crushing the cornflakes in a bag using a rolling pin.

Next, season the chicken mince and shape it into three patties.

Spread the crushed cornflakes on a plate and coat each patty on both sides until fully covered.

Bake the patties in the oven or air fryer at 200°C (392°F) for 15 minutes, or until crispy.

Meanwhile, chop the lettuce into small pieces, toast the buns, and spread mayonnaise on each one.

Finally, assemble the burgers by placing the patties first, then topping with lettuce.
