Pat dry your salmon fillets with a paper towel and salt to your preference then set aside.
In a small bowl, mix in your mayo and sugar really well and scoop an even amount on each salmon fillet on top. Spread so that the top of each salmon is covered in the mayo mixture.
Sprinkle your furikake on top generously then place it in the air fryer.
Cook at 400F for 10-15 minutes or until the top is nice and golden brown.
Serve on a bed of hot white rice and any veggies or salad you have at home and enjoy!
