Boil a pot of water. Score an X shape on your tomatoes, slightly piercing the skin. Drop tomatoes into boiling water for about a minute to a minute and a half.
Remove tomatoes from hot water and place into ice water. Once cooled, peel skin and cut tomatoes in half. Carefully trim off the soft flesh leaving the hard interior and seeds.
Combine aminos, water, and smoke into a bowl. Crumble nori sheet into mixture.
Place soft tomato pieces into the same bowl, evenly coat pieces and allow it to marinate in the fridge for 30 minutes.
Toast bagels then spread an even layer of cream cheese on bagels.
Now it's time to assemble. Place your "lox" on top of cream cheese and layer on the red onion, capers and chives. That's it!
