Slice snapper fillets in half to make four serves. Dip each in flour, egg and breadcrumbs. Place into hot oil. Cook on both sides until golden and crispy, before removing and placing on to a plate with paper towel to drain.
For the tartare: In a bowl, combine all ingredients.
To assemble burgers, place down cos lettuce, crumbed fish fillet, a couple of tablespoons of tartare sauce and the top of the burger bun. Serve straight away.
Notes
Any white-fleshed fish would work for these burgers
Light mayonnaise can be subbed in for whole egg, however a high quality mayonnaise will elevate the taste of your tartare
Another lighter tartare option: use one quarter cup whole egg mayonnaise with one quarter cup plain Greek yoghurt.
