Place all the cubed salmon into a bowl. Mix together the tamari, honey and brown rice vinegar and pour over the salmon. Mix and let marinate for 15 to 20 minutes.
Preheat your air fryer to 400 degrees. Air fry the salmon for 8 minutes, flipping halfway through.
For the smashed cucumbers:
Working on a flat, level work surface or cutting board, using a large chef's knife and the bottom palm of your hand, smash the cucumbers until they open and crack from top to bottom. Chop the cucumbers.
Place the cucumbers into a bowl with the carrots. Add in the sesame oil, coconut aminos, brown rice vinegar, garlic powder, season with Maldon sea salt flakes and the gochugaru. Mix together, taste and adjust anything as needed.
To serve: serve over a bowl of rice (if desired), top with the air fried salmon and add the smashed cucumbers on the side. Lightly drizzle with soy sauce and sesame oil if desired and feel free to sprinkle on a little furikake if desired. Enjoy!
