Place the Tuna, spring Onion, 1 lightly whisked egg, coriander leaves, coconut flour and a couple of grinds of salt and pepper in a food processor and pulse a few times to turn into a thick paste.
Shape the mixture into 12 patties and place in the refrigerator to chill for at least 30 minutes.
wipe down the food processor and add the flaxseed and sunflower seeds. Pulse a couple of times to break up the seeds until you have a very rough meal.
Mix the seeds with the almond meal and place in a shallow bowl.
Place the remaining 2 whisked eggs in the second shallow bowl.
Dredge the patties in the egg, then in the seed mixture to coat.
Heat at least 1cm of oil in a heavy-based frying pan over high heat. Fry the patties for 5 minutes on one side and 4 minutes on the other side until golden brown and cooked through.
Drain on paper towels and serve hot.
