Chop the tuna into very small chunks. To do this, I cut the tuna into thin slices, stack the slices and slice again, turn the stacks around and cut those slices into cubes. Once they are small like this, it is easy to then chop the tuna until it is quite small, like a mince. Add the chopped tuna to the ginger and garlic mixture and stir well to combine. Pop into the fridge for 20 mins
1 lb fresh ahi tuna
While the mixture is in the fridge, mix together the sweet chilli and mayonnaise and set aside
2 tablespoon mayonnaise, 1 tablespoon sweet chilli sauce
Wet your hands and shape the mixture into burger patties. I got about 6 out of my mixture. Try and have them about 1 inch thick to ensure even cooking.
Set your broiler to high. Brush the patties with some sesame oil, and pop onto a baking tray lined with aluminium foil. Pop the burgers under the broiler for about 6 minutes, turning halfway through (this will result in a medium rare burger - so adjust time to your liking). You really don't want to overcook, as this will result in a dry tuna burger.

To assemble the burger: spread a layer of sweet-chilli-mayo on your bun, top this with some lettuce leaves, a tuna burger, some cucumber salad (drain the cucumber first), and some crushed peanuts. Enjoy
